虚假目标干扰下的雷达网目标跟踪技术

摘要

In the presence of false target jamming,the SNR of the false target echo is higher and the measurements of the false targets can＇t be associated with measurements of the other radars.By using these characteristics of false target jamming,an algorithm is proposed,which is composed of the SNR test and the χ2 test.The simulation results show that the algorithm presented in this paper has a good performance on anti-jamming.%利用虚假目标量测存在信噪比高,且其他雷达的量测与虚假目标不关联的特点,提出了采用信噪比检验和卡方检验的雷达网抗虚假目标干扰算法,避免了其他雷达由于目标回波信噪比低未检测到此目标,而误将真实目标判断为虚假目标的问题。仿真结果表明此方法能够较好地鉴别出虚假目标。
