从检测概率评价隐身飞机抵近支援干扰性能
|
摘要
针对雷达在检测隐身飞机抵近支援干扰所掩护三代机时,如何构造有效模型对检测性能进行合理性评价,提出了一种基于俯冲抵近支援航迹的隐身飞机干扰模型。经过飞机姿态角解算,即时RCS序列提取,选用SwerlingIV分布,研究对比了飞机在正常飞行与隐身飞机抵近干扰状态下突防时雷达的瞬时检测概率时变特点。仿真表明:隐身飞机抵近支援干扰功率1 kW时能够有效使雷达检测概率降低72.5%,结合100万箔条干扰,可使三代机检测比降低至4.996×10–10,有效实现掩护三代机低检测概率突防。
Aiming at the problem of how to construct an effective model to evaluate the reasonableness of detection performance when a radar detects a third-generation aircraft covered by an approaching support jamming performance of stealth aircraft, a stealth aircraft jamming model based on diving to the near support track is proposed. After calculating the aircraft attitude angle, the time-varying dynamic RCS series are extracted. Using Swerling IV distribution, the characteristics of radar instantaneous detection probability time-varying in penetration jamming between normal flight and stealth aircraft are studied and compared. Simulation results show that the radar detection probability can be reduced by 72.5% when the stealth aircraft approaches the supporting jamming power of 1 k W. Combined with one million chaff jamming, the detection ratio of the third-generation aircraft can be reduced to 4.996×10–10, and the low detection probability penetration of the third-generation aircraft can be effectively realized.
