United StatesDescription
The Naval Air Warfare Center Weapons Division, China Lake is
located about 150 miles north of Los Angeles, and covers over a
million acres of Southern California's Mojave Desert. In 1943,
adequate facilities were needed for test and evaluation of rockets
developed by the California Institute of Technology (CalTech). At
the same time, the Navy needed a new proving ground for all
aviation ordnance. The Naval Ordnance Test Station (NOTS) was
established in response to those needs in November 1943. This vast,
sparsely populated desert, with near-perfect flying weather
year-round and practically unlimited visibility, proved an ideal
location not only for test and evaluation (T&E) activities, but
also for a complete research and development (R&D)
establishment as well. The early Navy-CalTech partnership
established a pattern of cooperative interaction between civilian
scientists and experienced military personnel that has made China
Lake one of the preeminent RDT&E institutions in the world. In
1967 NOTS became the Naval Weapons Center and now it is known as
the Naval Air Warfare Center Weapons Division, China Lake. There
are approximately 4,200 civilian employees, including 1,000
scientists and engineers, and 450 military personnel at China Lake.
The estimated annual budget is approximately $800 million.
Mission
NAWCWPNS provides technical and material
support to the fleet for land-based flight test and evaluation of
Navy weapons systems, conducts high-energy laser systems and
subsystems test and evaluation, serves as launch agent for
suborbital space systems and research rockets, and participates in
the operation of the DoD Missile Test Range at White Sands Missile
Range.

A biosignal measuring device that can include at least one Super-conducting Quantum Interference Device (SQUID) array (SQA) of High Temperature Superconducting (HTS) Josephson Junctions (JJs). The HTS JJs operating parameters can be adjusted to establish an anti-peak response for the SQA, that can be at a maximum along a defined response axis, for detection of extremely small biomagnetic fields. For operation, the SQA can be maneuvered around a target area of a stationary subject that is emitting biomagnetic signals using a stand with three degrees of freedom, so that the response axis remains orthogonal to the subject target area. The device can further include a radome with an atomic layer deposition (ALD) window on the radome surface. The radome ALD surface can allow for passage of magnetic signals through the ALD window and radome, while simultaneously preventing passage of infrared radiation therethrough

Aircraft ground effect altimeter for autonomous landing control
Description:
Embodiments of the invention use ground effect to determine how close an aircraft is to the ground. An electronic processor communicates with a navigation unit on an aircraft. The aircraft has an electronic instrument cluster for takeoff and landing control. An aircraft model is received from the navigation unit and used to compute aircraft modeled quantities. An initial altitude of the aircraft is received from a barometric altimeter. Initial aircraft velocities and initial aircraft orientations are from the navigation unit. The aircraft model is initialized. Accelerations, rotation, and altitude from the output of accelerometers, gyros, and the barometric altimeter are received. Surface and thrust control settings are received from the electronic instrument cluster. A best hypothesis for ground altitude is computed and the computed ground altitude having the lowest likelihood of error is reported.

An antenna having an active radome for beam steering and/or nulling in accordance with several embodiments can include at least one omni-directional radiating element, a radome surrounding the radiating element, and a network of conductive segments that can be placed between the radome and radiating element. A plurality of switches can interconnect the conductive segments to form the network. The switches can be FET, MOSFET and optical switches, and can be selectively closed when the element radiates or receives RF energy to selectively establish connectivity between the conductive segments, which can achieve a selective Yagi-like effect for the antenna. The conductive segments network can have any geometric profile when viewed in top plan, such as octagonal, square and the like, provided the segments surround the radiating element. A processor can be used to provide a control algorithm, which can contain non-transitory written directions that selectively activate and deactivate the switches.
An apparatus allows a sample mounted within a temperature controlled radome system to be tested. The apparatus maintains the sample under controlled temperatures and allows radiation from a radiation source to expose the sample to broadband electromagnetic radiation of varying power, frequency and angle of incidence
An improved tapered slot antenna. The structure includes a first antenna element, a second antenna element, a brace, a semi-infinite balun and a radome. The first and second antenna elements are operatively coupled to the brace in a tapered slot antenna configuration. The first and second input feed of the semi-infinite balun are operatively coupled to the first and second antenna elements, respectively, so that the second input feed is situated along substantially an entire length of a feed channel of the second antenna element. The radome is operatively coupled to the first and second antenna elements. A method for fabricating improved tapered slot antennas is also described
Apparatus and method for cooperative multi target tracking and interception
Description:
The invention described herein provides an apparatus and a method to cooperatively track and intercept a plurality of highly maneuvering asymmetric threats using networks of small, low-cost, lightweight, airborne vehicles that dynamically self-organize into an ad hoc network topology. This is accomplished using distributed information sharing to maintain cohesion and avoid vehicle collisions, while cooperatively pursuing multiple targets.

Apparatus for and method of forming multiple simultaneous electronically scanned beams using direct digital synthesis
Description:
The apparatus/method according to the present invention accomplishes a reduction in the total number of direct digital synthesizers (DDSs) needed for use in electronically scanned antenna array to generate multiple simultaneous radio frequency (RF) beams. The apparatus includes, inter alia, a multi-beam forming synthesizer, a plurality of DDSs, a corresponding plurality of amplifiers all operatively connected to a plurality of radiating elements of the antenna array. This arrangement uses a single DDS per radiating element. Each DDS uses a composite amplitude, phase and frequency information computed by the multi-beam forming synthesizer to create the proper waveform for driving the antenna array, and accordingly, generating the desired multiple simultaneous RF beams, i.e. 1-M (e.g. 1 through M) RF beams each of which can have a different frequency and separate modulation.

Ball joint gimbal system
Description:
A ball joint gimbal system which provides for a precise line-of-sight stabilization of a gimballed mirror that rides on a ball and its associated support structure. The mirror is positioned by four braided lines. The brained lines are driven by four servo motor with each servo motor being coupled to one of four capstan shafts. Each of the braided lines is wound around one of the four capstan shafts. The braided lines are positioned by optical shaft encoders. The low inertia of the gimballed mirror and the positioning of the mirror by the braided lines result in an extremely accurate and fast scanning optical pointing system. Inertial gimbal stabilization of the line of sight to a target is by a stabilization algorithm utilizing body rate information from body sensors which are components of the missile for providing autopilot and navigation functions for the missile.

Combined coherent and incoherent imaging LADAR
Description:
A long range eye-safe laser radar (LADAR) system for use in an environment where real-time non-cooperative identification of an object is required. In particular, a laser beam is aimed at an object, the laser energy reflected from the object is collected by a detector array for use in generating a composite of both a high resolution 3-Dimensional (3D) shape of the object and the object's high resolution micro-Doppler vibration spectrum, a characteristic of the object as unique as a fingerprint. The composite is then used to automatically identify the object by comparison to a database of similar composite sets of 3D shape and vibration spectrum information with the results of the identification conveyed to the user.
