摘要 针对远距离支援干扰(SOJ)压制和距离欺骗复合干扰下目标检测概率下降及虚假目标造成数据关联错误的问题,提出了基于等效量测的雷达网目标跟踪算法。首先,将各雷达得到的量测进行分组;然后,将同一部雷达对相同目标的角度量测进行数据压缩,并利用交叉定位的原理得到等效量测;最后,利用等效量测进行目标跟踪。算法关键在于利用最小二乘法构建用于跟踪的等效量测,降低数据处理载荷,剔除虚假目标。仿真结果表明:在SOJ压制和距离欺骗复合干扰下,该算法使得组网雷达对真实目标进行稳定跟踪。 An algorithm of target tracking for radar network based the equivalent measurements is proposed in view of the problems that target detection probability decreases and false targets causes data correlation error under the compound jamming of stand-off jamming oppression and distance deception. First, the measurements from every radar are divided into groups. Then the angle measurements of the same target from the same radar are compressed, and the equivalent measurements are got ton by the principle of crossing bearing. Finally, targets are tracked under the equivalent measurements. The key of the algorithm is to construct the equivalent measurements for tracking by using the least squares method, so as to reduce data processing loading and eliminate false targets. The simulation results showed that the algorithm could stably track targets for netted radars under the compound jamming of SOJ oppression and distance deception.
