抗ARM攻击告警诱偏系统时序控制方法

A Sequential Control Methodon Alarming-Decoying System for Anti-ARM Attacking

摘要:

针对诱偏系统由于站间距离、时序控制等因素造成诱饵信号、雷达信号在时域上存在差别,无法对反辐射导弹(anti-radiation missiles,ARM)进行有效诱偏的问题,提出了告警诱偏系统时序控制模型及近似模型,通过时序控制使各诱饵信号到达ARM雷达口面的时刻近似相同,大大减少了诱饵信号前沿超前时间,增加了ARM前沿检测区分信号的难度。根据ARM前沿检测区分信号能力,分析了传统时序控制方法下典型诱偏系统的有效诱偏区域；利用告警雷达提供的ARM位置信息,提出告警诱偏系统时序控制模型；根据实际告警雷达工作性能,提出告警诱偏系统时序控制近似模型。仿真试验验证了该方法的有效性和实用性。

Abstract:

For the difference of decoy and radar signal in the time domain, decoying system is difficult to disturb ARM effectively. Sequential control model of alarming-decoying system was proposed in this paper. Decoy signals reached ARM radar at the approximately same time through the sequential controlling. Because the time of decoy signals edge ahead was greatly reduced, the possibility of resolution was reduced. Firstly, according to ARM edge detection ability to distinguish the signal, effective decoying region of typical decoying system was studied under the traditional sequential control method. Secondly, sequential control method on alarming-decoying system was introduced using the angle and distance information of the ARM. Thirdly, the method was introduced only using the angle information. Finally, the simulation results verified the validity and practicability of the method.
