扩展比值插值算法的雷达测距、测速精度分析

Analysis of Radar's Distance and Speed Measure Based on Algorithm of Expand Ratio and Interposal Measurement

脉冲多普勒雷达在进行距离/多普勒测量时,如果按照常规方法直接取距离响应主瓣/多普勒响应主瓣的最大值解算探测目标的距离和速度则测量精度难以有效提高,为了提高参数测量精度,需要对主瓣进行插值处理,针对扩展比值插值算法对雷达测距、测速的精确度进行了分析。

In the process of PD radar measuring the target＇ s distance and speed, if the peak value of echo and frequency spectrum are applied to measure target＇ s distance and speed, the maximum measure precision will not be attained, so the algorithm of expand ratio and interposal measurement may be used to increase the precision of distance and speed. The measure precision of the target＇ s distance and speed measurement are analyzed herein.
