Determining Range and Velocity of an Object

US PATENT # 7,755,536 Method of Signal Processing for Determining Range and Velocity of an Object 
US PATENT # 7,545,325 Method of Signal Processing

This technology combines two patented methods for finding range and velocity of a transmitter in a radar system using a time scale factor. The first technology (7,545,325) determines the position and velocity of a transmitter over a wide range of bandwidths, wherein the position and velocity are determined using a scalar relationship dependent on the radial velocity of the transmitter with respect to the receiver. The second technology (7,755,536) models the Doppler process as a time shift and change of scale of the original signal. Unlike other methods, this combined process resamples the signal at a rational multiple of the original sample rate, enabling efficient implementation of the scale correlation function.
