雷达测速中的 Robust 技术

精确测定初速仍然是弹道测量最重要的任务之一。现代多卜勒雷达尽管很实用,但对于处理实际数据还存在许多缺陷。本文运用Robust估计的现代统计法,通过改进原某测速雷达中的数据处理部分,达到即使在最不利的条件下也可以计算出其精度能估计的初速度。使用同一方法还可以确定阻力系数。实验结果证实了这些结论。

Robust Technique in Speed Measuring with Radar

Exactly measuring the raw speed is still one of the most important tasksin trajectory measuring. Modern Dopplar radar is of practical use, but thereare many weak points in processing practical datum. This paper uses modernstatistical method, called "Robust estimation", to calculate the first speed, theprecision of which can be estimated, even in the worst condition by improvingthe data processing in the raw speed measuring radar. With the same method,the coefficient of resistance can also be determined. The experiments have heenproved to be of these correct conclusions.
