【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。更多还原

【Abstract】 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 3 D radar and 2 D radar. The distance and azimuth information between target and 2 D radar are estimated by making use of the measurement of 3 D radar. By comparing the estimated values with the measurements of 2 D 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 2 D radar accuracy on algorithm’s discrimination probability. Simulation results show that the proposed method is efficacious in discriminating the false-target jamming.更多还原
