Analysis of Decoying Radar Interception System Simulation of UAV

诱偏技术是电子对抗中自我保护的有效方法。在分析电扫恒差比幅测向原理的基础上,讨论了设置诱饵情况下无人机截获系统测向的误差;在射频仿真系统中,对诱饵、雷达与无人机的相对位置关系进行了研究,给出了算法,最后通过仿真对其进行了验证。这对电子对抗中武器系统诱偏技术的应用、射频仿真系统功能完善以及武器系统作战效能评估等研究都具有一定的参考价值。

Decoying technology is an effective manner to self - protection in electronic countermeasures. Based on electronic scan constant difference amplitude comparison direction measurement（CDAC） theory, the error formula of constant different amplitude comparison direction measurement in radar interception system of UAV is discussed under the condition of decoy . In radio frequency simulation system , the relative position relations about decoy and radar on the array is discussed , a resolution arithmetic is given and its validation is finished. Finally, the simulation results prove that the method has important reference value for applying the decoying technology in electronic counterineasures, improving radio frequency simulation system and evaluating weapon system battling efficiency .
