1. A method for improving detection ground moving targets via post-pulse compressed data space time adaptive processing (Pμ-STAP) processing, the method comprising:
receiving, by a radar detection system, one or more input radar waveforms;
processing, by the radar detection system, the one or more input radar waveforms to produce a pulse compressed datacube;
applying, by the radar detection system, a plurality of homogenization filters to the pulse compressed datacube to produce a plurality of homogenized pulse compressed datacubes;
generating, by the radar detection system, an output covariance matrix based on the plurality of homogenized pulse compressed datacubes;
executing, by the radar detection system, a partial adaptation process against the output covariance matrix;
initiating, by the radar detection system, space-time adaptive processing with respect to the pulse compressed datacube and an output of the partial adaptation process to identify one or more candidate targets of interest, wherein the space-time adaptive processing is configured to identify one or more candidate targets of interest by filtering the pulse compressed datacube based on the output of the partial adaptation process; and
detecting, by the radar detection system, one or more targets of interest from among the one or more candidate targets of interests identified by the space-time adaptive processing.
