A radar signal target detection and display system employs feedback to produce improved detection and tracking. Portions of the radar images for each antenna channel to search for the target of interest are defined using the track state to define the center of the search region and using the track covariance matrix to define the size of the region. Moving reference processing (MRP) is performed. MRP employs a search centered on the motion state derived from the detection sent to the tracker on the previous coherent processing interval (CPI). Space-time adaptive processing (STAP) is employed on each CPI using a unique set of adaptive degrees of freedom (DOFs) derived from pre-MRP and post-MRP complex radar image amplitudes for each antenna channel.
