摘要

本文研究相控阵雷达中的重复录取现象和为消除这种现象所采用的观测数据预处理方法．首先研究了出现重复观测的概率随信噪比和波位间距等参数变化的规律．而后在重复观测预处理算法中引入最大合并数和合并距离的先验信息，以减小错误合并概率．最后，研究合并前后的观测误差．比较了这种合并方法与不加任何约束合并算法的性能

Abstract

The phenomenon of observation multiplicity for the phased-array radar is studied and a prepro cessing algorithm to eliminate the redundant observations is proposed.At first

the probabilities that redundant observations exist are derived.It is shown that these probabilities depend on signal-to-noise-ratio and the spacingbetween the adjacent beams.Second

a priori knowledge of the maximum number of observations to be merged and the maximum merging range is introduced to the pre-processing method.At last

the measurement’s error be fore and after mergence is calculated

and the performance of this method is compared with those methods without any limitations.
