摘　　要：针对机载雷达在空空作战时的作用距离仿真问题,建立了不同态势下的作用距离仿真模型。首先分析了影响机载雷达空空作用距离的影响因素,然后结合目标的雷达截面积模型,针对脉冲多普勒雷达体制的特点,分析主瓣杂波、副瓣杂波和高度杂波对雷达信号检测的影响,分别从上视、下视迎头接近和下视尾追等不同态势建立了相应的雷达作用距离模型。仿真结果表明了所提方法的合理性与有效性。Aiming at the problem of airborne radar range simulation in air-to-air operation,range simulation model was built by different situation.Firstly,influencing factor of airborne radar range was analyzed.Then the factor of radar signal detection from mainlobe clutter,sidelobe clutter and altitude clutter was analyzed,aiming at the character of pulse-Doppler radar system,combining with target’s radar cross section model.Radar range model was built accordingly to different situation such as looking up,looking down for a nose-aspect approach and looking down for a tail chase.The simulation result verified the feasibility and validity of the model.
