ABSTRACT:
Various embodiments are described herein for a moving target detector that processes input data to perform detection for a current range cell. The moving target detector includes a Doppler filter bank module for processing the input data to provide several Doppler outputs for the current range cell, a no-land-clutter path for processing several input data sets related to the several Doppler outputs to provide detection data by performing peak selection on each of the several input data sets and performing detection on the results of the peak selection, a land-clutter path for processing the several input data sets to provide detection data by performing Constant False Alaπn Rate (CFAR) detection on each of the several input data sets and merging the detection results; and a switching logic module for selecting one of the land-clutter path and the no-land-clutter path based on clutter information.
