雷达组网抗距离-速度欺骗复合干扰技术研究

Antijamming Technique in the Presence of Range-Velocity Deception Compound Jamming Based on Radar Network

利用距离多假目标-速度欺骗复合干扰下虚假目标检测概率高、与真实目标角度量测相近的特点,提出了基于雷达组网的低可观测目标跟踪方法。首先根据角度量测信息完成各雷达量测集的划分与融合,然后进行雷达量测划分同源假设检验,利用虚假目标所暴露的真实目标的角度信息,构造低可观测目标的量测输入,提高目标跟踪的稳定性,最后利用目标速度估计径向投影与速度量测的差异鉴别速度欺骗干扰。仿真结果证明了该技术的可行性和有效性。

A low observable target tracking method based on radar network is proposed in the presence of the property of range-velocity deception compound jamming which has high detection probability and similar angle-measurements to the target. Firstly, the angle-measurement set of each of the radars is partitioned according to the angle information and the measurements within the same partition are fused. Then the hypothesis testing for the same source measurements of each partition is realized. Finally, velocity deception jamming is recognized according to the diversity between the radial projection of target velocity estimation and the radial velocity measurement. Simulation results verify the feasibility and validity of the proposed algorithm.
