基于目标特性的智能通道选择检测算法研究

Study on Intelligent Auxiliary Channels Selection Detecting Algorithm Based on Targets Characteristics

空间阵列在探测地面动目标时会遇到极强地杂波,使得无法有效探测目标。传统波束域降维空时自适应处理算法采用固定辅助通道选择方法,而没有考虑目标的运动特性,所以对于杂波对消效果欠佳,导致检测性能不够理想。为解决上述问题,在波束域降维空时自适应算法的基础上,提出一种综合考虑目标运动特性的自适应辅助通道选择算法,能够有效改善输出信干噪比,提高目标检测概率,仿真结果验证了改进算法的有效性,可以应用到空间阵列探测地面动目标的场景。

Based on beam space dimension space-time adaptive algorithm, a kind of STAP algorithm was put for- ward, which takes the target motion characteristics of adaptive auxihary channel selection algorithm into considera- tion. The proposed algorithm can effectively improve output SINR and the target detection probability. Simulation re- suits verify the validity of this algorithm which can be applied to spatial array in ground moving target detection scene.
