反辐射无人机对抗雷达诱饵阵方法研究

Research on anti-radiation UAV against radar decoy deployment

为了研究反辐射无人机攻击雷达诱饵系统的有效技战术方法,分析了诱饵系统的诱偏机理,建立了导引头测角模型。基于3诱饵布阵下信号传播时间差和发射时序差,在无人机飞行条件下对诱偏空域和测向偏差角数据进行仿真。分析发现,信号传播时间差使得同时发射诱偏信号的诱偏空间存在单诱饵暴露区,采取垂直入侵方式可以破解;控制发射时序差可以实现同步闪烁诱偏,飞控系统按照闪烁周期间隔采样测角数据可以锁定某部诱饵实施摧毁。研究结果对于从技战术角度来改进提高反辐射无人机攻击效能具有一定指导意义。

In order to study the effective technical and tactical methods of the anti-radiation UAV(ARUAV)attacking the radar decoy system,the mechanism of decoy system is analyzed and the seeker angle measurement model is established.Based on the signal propagation time difference and launch timing difference under the deployment of 3 decoys,the decoy airspace and direction-finding deviation angle data are simulated under the flying conditions of the UAV,and it is indicated that there is a single decoy exposure area in decoy space for simultaneous launch of decoy signals due to the time difference of signal propagation,which can be cracked by vertical intrusion.The launch timing difference is controlled to achieve the synchronous flicker decoy,and the flight control system samples the angle measurement data at the flicker period interval to lock and destroy a certain decoy.The research results are of certain guiding significance to improve the ARUAV attack efficiency from the technical and tactical perspective.
