采用脉冲多普勒体制的地面雷达在距离上是模糊的,这就要求在信号处理上进行距离模糊解算。文中首先提出了一种参差加抖动解距离模糊方法,并把该方法与常规3/7准则的性能进行对比分析,指出了该方法在满足PD性能的同时大大提高了雷达数据率。然后对该方法的应用场合进行分析,对该方法的实际应用具有一定的指导意义。

Ambiguity resolution is necessary in signal process as a consequence of the range ambiguity in ground-based radar of PD system.So,a novel method,PRI staggering and wobbling,for resolving range ambiguity is presented.Comparison to the routine 3/7 detection criterion,this algorithm can meet the capability of PD and improve the radar data rate consumedly.Then the application fields of this method is shown in the paper,which can provide some guiding significance for this algorithm.
