摘　　要：针对波束控制随着技术体制的发展有可能失效的问题,对时差定位电子侦察飞机的有源对抗技术进行了研究.首先,研究了时差定位体制电子侦察飞机的时差信息估计方法,然后,分析讨论了对双机实施有源噪声调频干扰可以有效地对抗时差定位体制电子侦察飞机,干扰后可形成虚假的时差估计信息,通过时差组合形成更多的虚假位置,达到对抗的目的.最后,通过仿真实验验证了上述对抗技术的有效性,为主动对抗时差定位电子侦察飞机提供了技术参考.In this paper we focus on the problem that the beam control can be failure with the development of technical system, and research the active countermeasure technology for the electronic reconnaissance aircrafts with TDOA location. Firstly, we research the estimation method of time difference information for the electronic reconnaissance aircrafts with TDOA location system, and then discuss that implementing the active noise FM jamming for bi-aircrafts may counter effectively the electronic reconnaissance aircrafts with TDOA location, as the false TDOA estimate information can form more false positions after jamming, thus achieving the goal of counter. And finally, by simulation experiments, it proves the above-mentioned countermeasure technologies to be effective, which provides a technical reference for positive countering the electronic reconnaissance aircrafts with TDOA location.
