摘　　要：同构体系下组网雷达配置方式简单,抗欺骗式假目标算法单一。该文提出一种异构组网雷达系统抗欺骗式假目标方法,对于既包含两坐标雷达又包含三坐标雷达的异构组网雷达系统,首先利用三坐标雷达对目标进行定位,计算目标相对于两坐标雷达的距离、方位角信息。然后,将该计算值与两坐标雷达对目标的量测值进行比较,通过构造卡方检验对真假目标进行有效鉴别。仿真结果表明,该算法可以有效地鉴别欺骗式假目标,并分析了欺骗距离、目标量测个数和雷达测角精度对算法鉴别概率的影响。The existing algorithm against deception-false-target by homogeneous radar system is single due to the simplicity of configured mode.To solve the problem,a method against deception-false-target based on isomerous netted radars is proposed.The isomerous netted radars in this paper consists of 3D radar and 2D radar. The distance and azimuth information between target and 2D radar are estimated by making use of the measurement of 3D radar.By comparing the estimated values with the measurements of 2D radar,the false-target can be discriminated by using chi-square statistics.We further analyze the influence of the distance of deception distance,observation frequency,the 2D radar accuracy on algorithm’s discrimination probability.Simulation results show that the proposed method is efficacious in discriminating the false-target jamming.
