Clutter suppression and moving target indication with airborne wide-area surveillance radar

An accurate description of the ground clutter amplitude and power spectral probability density function is important for robust target detection. One goal of this paper is to present a common distribution which matches the Ku-band data sets obtained from GMTI mode. Then a mDT-STAP method was used to suppress clutter, which, in fact, has better performance to detect moving targets. After clutter suppression, the CFAR approach was used to detect moving targets. The data used in this paper is the real data in GMTI mode by an airborne search radar. By utilizing the radar echo data of airborne radar, the location and velocity of the moving targets, can be achieved.
