摘要
针对距离多假目标欺骗干扰下多基地雷达系统,提出一种基于同源定位检验的抗欺骗干扰技术。首先,各接收站对获取到的目标角度量测进行预处理,划分出同一方位向上目标并进行数据压缩,以此提高同一方向上目标角度量测精度;同时,利用发射站和接收站组成的双基地雷达系统进行目标定位;最后,将各站定位结果进行同源定位检验,并融合检验后结果。仿真结果表明:该方法能有效抑制距离多假目标欺骗干扰,并能对多目标进行精确定位。
To counter multi-range-false-target deception jamming, an anti-jamming technique based on homologous localization examination has been proposed. First, the azimuth angle measurement of target is pre-processed in each receiver to group the targets that exist in the same direction. Then data compression is implemented in order to improve the accuracy of angle measurement. At the same time, with the combination of one transmitter and one receiver, target localization of the bistatic radar system is implemented. Finally, homologous localization examination is performed using the localization results from each receiver, after which targets position can be estimated by position fusion. Simulation results verify that the proposed method can suppress the deception jamming effectively and realize the localization of multiple real targets with high precision.
