Abstract
A time efficient method for processing digitized doppler radar signals and establishing adaptive target detection thresholds which are used to distinguish targets from noise and clutter. After subdividing the range-doppler matrix into several equally-sized parallel processing elements, the radar system's signal processor executes this process on each processing element in parallel. This process involves the processing of the digitized radar signals stored in each parallel processing element by integrating over the amplitudes of each data cell in a given parallel processing element. This, in turn, yields a secondary data array for each parallel processing element equal in dimension to the parallel processing element itself. Target detection thresholds for all cells in each parallel processing element can then be established from the values stored in these secondary data arrays. This process is time efficient in that the number of signal processing steps needed to establish the target detection thresholds for each and every data cell in the range-doppler matrix is independent of the number of targets and unique noise, clutter regions in the surveillance area.
