传统的单雷达目标检测算法在低信杂噪比(SCNR)场景下,其检测性能较差,对低空微弱目标检测时,由于杂波信号很强,目标回波信号可能在单个雷达的回波中被杂波淹没,导致不能检测到目标。所以,文中提出一种多雷达信号融合算法检测动目标,在距离多普勒域对多个雷达回波信号进行融合,增强目标信杂噪比。最后,通过仿真来验证提出的算法的有效性。

In the low signal-to-clutter-noise ratio (SCNR) scenario, the performance of the conventional target detection algorithms based on single radar will degrade. When detecting the weak targets in low altitude, since the clutter is trong, the echo signal of weak targets will be submerged in single radar, thus, weak targets will not be detected. To solve this problem, a multiradar signal fusion algorithm for moving target detection is proposed in this paper. Multi-radar signal will be fused in range-Doppler domain, and the SCNR will be improved. At the end of this paper, the effectiveness of the proposed method will be demonstrated by simulation.
