Modified space-time adaptive processing for dismount detection using synthetic aperture radar

This paper presents a new adaptive radar signal processing technique for dismount detection using Synthetic Aperture Radar (SAR). The new approach uses the complex nature of the Doppler response scattering from the dismounts rotary motion to modify the conventional Space-Time Adaptive Processing (STAP). This is used for dismount detection wherein resolution is dictated by the sensor system platform. The feasibility of the modified STAP (M-STAP) is demonstrated by simulations and by applying it to the Gotcha data set for dismount detection.
