摘要
本文介绍了脉冲多普勒雷达的距离—多普勒杂波功率谱计算方法 ,针对杂波仿真中存在的精度和实时性之间的矛盾 ,提出一种新的杂波功率谱实时计算方法 ,即事先存储部分计算量较大的面积单元数据 ,然后实时构造杂波功率谱 .该方法既保持了非实时算法的高精度 ,又满足了实时性要求 ,计算时间小于 10 0ms.
A range-Doppler clutter power spectrum density (PSD) computation method for pulse Doppler radar is introduced in this paper. For the contradiction between precision and rapidity in clutter-simulation, a novel and real-time computation method is proposed for clutter PSD, with which the data of the area units are pre-stored and then the clutter PSD is reconstructed at real time. High precision and high speed (The time of clutter PSD computation is less than 100 ms.) are achieved by applying this method.
