摘　　要：组网雷达凭借信息融合的优势具有优越的抗干扰性能,传统针对单部雷达的欺骗干扰方法对组网雷达将失去作用。针对这一问题,在分析组网雷达数据处理方法的基础上,得出使网中各雷达对假目标观测的空间状态差异保持在雷达网检验门限范围内,组网雷达系统就不能有效地剔除假目标的结论。通过仿真研究分析了对组网雷达的距离多假目标欺骗干扰效果以及影响干扰效果的因素,在此基础上对干扰机应采取的信号调制措施进行了仿真。仿真结果证明该干扰方法的有效性与可行性。Netted radar has distinguished performance in anti-jamming due to its advantages on information fusion. The traditional false-target method for single radar jamming is useless to the netted radar. In order to solve this problem, we analyzed the netted radar＇s data processing method and came to a conclusion that if targets＇ different states observed by each radar in the radar network are kept in the range of the threshold which is distinguished the true and false targets, the netted radar can＇t reject the false targets effectively. The jamming effect and the effect factors were simulated and studied. The methods for signal modulation of jammers were simulated. The simulations reveal that this method is effective and feasible.
