Integrated Radar Optical Surveillance and Sighting System (IROS3) Technology

Naval Surface Warfare Center, Crane Division’s integrated radar optical surveillance and sighting system (IROS3), chosen as the Department of the Navy’s (DON) 2010 DON TTIPT video award recipient, was given the opportunity to have a video profile created by the Office of Naval Research’s photographer/videographer, John Williams of Jorge Scientific. During the November 13-16, 2010, DOD TTIPT Workshop held in Philadelphia, Pa., attendees were able to view the completed video and learn more about the technology.

Born out of the USS Cole tragedy in October 2000, when the United States Navy destroyer was attacked by a suicide bomber during harboring for refueling in the Yemini port of Aden, the IROS3 technology was developed in response to the increasing threats to high dollar value and exposed naval equipment. The proven and demonstrated system provides the capability to surveil, track, and actively respond to threats or to deter threats in a manual or semi-automated fashion using nonlethal and lethal responses. "Critical infrastructure assets"—or those physical systems that are critical to the minimum operations of the economy and government, high dollar-value assets, with a large or complex protection area and exposed to a higher than standard risk—would benefit from the scalable and adaptable IROS3 system.

The core of the system consists of an intuitive user interface coupled with software drivers for external devices (i.e., cameras, spotlights, and audible warning systems) and a digital input/output card capable of up to 32 connections. The system can replace many different and unique human interface devices with a single and standardized system, allowing for aggregation and presentation of data from multiple sources to the user for response. It provides a common tactical scene that allows a ship to maintain 24-hour situational awareness, providing shipboard protection from asymmetric threats while pierside, at anchor, and transitting restricted waterways where navigation and detection systems (other than navigational radar) are restricted, prohibited or secured.

The IROS3 system gives the user flexibility to "detect and track," "warn," "track and identify," and "engage" the threat if deemed necessary.

A nonexclusive patent license agreement was signed with Nextwave Systems for one of the six protected patents.
