摘要
脉冲多普勒雷达在目标检测时常常存在距离模糊问题,目前比较成熟的解距离模糊算法有一维集算法和余差查表算法。在一维集算法的基础上,提出了一种改进的脉冲多普勒雷达解距离模糊新算法。该方法具有运算速度快、实时性能好的特点。通过对四目标距离模糊解算仿真和实际应用结果表明,该算法与一维算法相比运算时间减少了48%,验证了其高效性和有效性。
One-dimension method and Residues＇ difference look-up table method are applied usually against range ambiguity often occurred in target detecting of pulse Doppler radar.An improved algorithm is put forward based on the one-dimension algorithm for range ambiguity of PD radar.The new algorithm has advantages of faster operation and better real-time performance over the one-dimension algorithm.The simulation and result of practice on four target range ambiguity resolution indicates that the new algorithm only takes 52% time of that the one-dimension method takes,which validates the high efficiency of the method mentioned.
