摘要
利用隐身飞机光学窗口的"猫眼"效应,采用激光雷达对其有源精确定位的方法,给出了系统构成及定位流程,计算了背景辐射的影响,结果表明此种影响可不予考虑。介绍了由接收机探测阈值确定发射峰值功率阈值的方法,选定了系统工作参数,结果表明,此系统可在3s内将目标精确定位至2m×2m(8km)或2.5m×2.5m(10km),满足后续对其致盲或摧毁的战术要求。
A method is presented to locate stealth aircraft precisely by laser radar based on the cat eye effect of optical window of stealth aircraft, while the detecting system component and locating flow chart are given. The effect of background radiation is calculated, and results show that the effect can be neglected. A new method is proposed, which determines the detecting threshold of receiver by the power threshold of emission peak value. The working parameters of laser radar are chosen. The result shows that the target can be located precisely within a square of 2 m×2 m at the distance of 8 km or 2.5 m×2.5 m at the distance of 10 km, The precision can meet the location requirement of laser blinding or destruction toward optical window of stealth aircraft.
