摘要

时空自适应处理(STAP)技术被广泛应用于抑制强干扰(杂波和其他电子对抗措施的联合效应)的影响。在文献中提出了有限信道和降阶STAP技术，以解决全自适应STAP中存在的计算问题。本文研究了在杂波存在下地面移动目标指示(GMTI)场景下，双通道ΣΔ (SigmaDelta)-STAP检测多目标的性能。杂波模拟来自一个机载平台，工作频率为10ghz，脉冲重复频率为5khz。首先，利用Σ Δ-STAP有效检测单个地面移动目标。进一步，将该算法应用于检测速度分别为7.5 m/s和15 m/s的两个目标。此外，考虑了五个目标场景，Σ Δ-STAP算法成功检测到这五个目标，

Multiple Target Detection using ΣΔ-STAP in the Presence of Airborne Clutter

Spatio-Temporal Adaptive Processing (STAP) technique has been widely applied to mitigate the effects of strong interference (joint effects of clutter and other electronic counter measures(ECM)). Limited channel and reduced rank STAP techniques are alternatively proposed in the literature to address the computational issues present in fully adaptive STAP. This paper investigates performance of two channel ΣΔ (SigmaDelta)-STAP for detecting multiple targets in Ground Moving Target Indication (GMTI) scenario in the presence of clutter. Clutter is simulated from an airborne platform operating at 10 GHz and a pulse repetition frequency of 5 kHz. First, a single ground moving target is detected effectively using the Σ Δ-STAP. Further, this algorithm is applied to detect two targets moving with 7.5 m/s and 15 m/s velocities. In addition, five target scenario is considered and the Σ Δ-STAP algorithm successfully detected these five targets,
