Title: Stap based ground moving target detectability in the airborne/spaceborne array radar
Abstract: A space-time adaptive processing (STAP) can be effective in detecting the ground moving targets from the airborne/spaceborne moving platform in the severe ground clutter and jammer environments. In this paper, the characteristics of target, ground clutter and jammer signals are analyzed and designed the adaptively weighted clutter notch filter in two dimensional spatial and temporal azimuth angle-Doppler domains. The simulation is performed for ground moving target detection by rejecting both clutter and jammer simultaneously through the STAP processing. The probability of target detection is investigated depending on the SNR and the minimum detectable velocity (MDV) in the given false alarm rate. The simulation results show that the MDV can be ideally achieved up to 2 m/s ~ 3 m/s at the 90 % of detection probability in the given false alarm rate of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> and 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-6</sup> . This technique may be applied for the surveillance and traffic monitoring of moving vehicle on the road.
