Abstract :
The problem of space time adaptive processing (STAP) is approached in a two step process, filtering and detection. For a certain look direction, the signal strength is estimated by a least squares technique. The receiver scans through all possible look directions and returns estimates of the signal strength. From this map, we can employ standard detection techniques (such as CFAR) to extract targets.
