Abstract
A radar system with enhanced processing for increased contrast ratio, improved angular separability and accuracy, and elimination of ghost targets. The radar system is equipped with transmitters, receivers, pluralities of transmit antennas, and pluralities of receive antennas. The enhanced processing chain on-board the radar system iteratively detects target(s) by first finding the strongest target, subtracting the estimated received signal from the detected target, and repeating the process for subsequent targets until a predefined number of iterations is completed or an exit condition is tripped. The enhanced processing chain's subtraction increases the contrast ratio of detectable targets. The detection is thus refined by determining optimal azimuth, elevation, gain, and phase of each detection through a joint optimization of all detections. The subtraction and refinement aid in eliminating ghost targets by removing sidelobe signals and residual errors that cause ghost targets to appear.
