对空情报雷达网密集假目标干扰机理分析

针对雷达网欺骗干扰问题，首先讨论了雷达网数据关联处理方法薄弱环节，给出了可以欺骗雷达网的假目标应该满足的条件，然后分析对空情报雷达网密集假目标干扰的产生机理和作用机理，为产生高逼真的假目标，将空间分布转化为非线性最优化问题。当进行多干扰机协同干扰时，将干扰机功率资源在空间的分配问题转化为非线性规划问题。仿真研究了对网络化雷达的假目标欺骗干扰效果以及影响干扰效果的因素，该结果可为对空情报雷达网电子对抗提供理论指导。

Mechanism analysis of air surveillance radar network system dense false target jamming

The weakness of data processing algorithms for radar network is discussed,requirements of false targets for combating the victim radar network is given. Then the mechanism of dense false target jamming against radar network is analyzed. The false target distribution is transformed into a nonlinear optimization in order to generate the false target acting like a real target. For multiple jammers scenario,power resource allocation is turned into a nonlinear programming. The effectiveness of jamming is simulated and the influence factors are studied. This research will provide a theoretical guidance for the radar network electronic countermeasure(ECM).
