摘要
针对某型机载预警脉冲多普勒体制雷达本身的缺陷,对径向速度边界值进行计算,对盲区进行建模,对影响机载雷达盲区大小的各参数进行分析并进行仿真,结果表明模型能够准确地反映该型雷达的探测盲区。该模型已应用于作战训练,实践表明模型能帮助战勤人员了解战场态势,判断特定目标是否进入盲区,有利于战勤人员根据理论盲区指示采取相应的情报处理和协同处置措施,以便对重要目标进行跟踪和监视。如果敌方使用该型雷达,模型也可以作为突袭敌方目标时的理论基础依据。
Aimed at the problems of an airborne warning pulse Doppler（PD） radar,this paper calculates the boundary value of radial speed,sets up model of the blind zone,and analyses each parameter influencing on the area of airborne radar blind zone.Then,some experiments are made,and the experimental results show that the model can reflect the airborne radar blind zone accurately.The model has been used in operational training,and the results indicate that the model can help the airman to know well battle field situation and to forecast whether the special targets are moving into the radar blind zones or not.It is propitious to take some measures before the targets move into the radar blind zones.If the enemy uses this type of radar,the model can be also used as the theoretical foundation of attacking enemy targets.
