分布式辐射源视在中心位置精度分析

Several Factors Affecting the Apparent Centre Position Precision in Distributed Radiating Sources

在寻的制导射频仿真系统的建设中,分布式目标辐射源是最为常见的一种形式,它是仿真系统中的一个重要组成部分。飞行目标的回波特征需在其上复现,而其中的目标实在位置的准确设定是一个基本问题。本文就目标的定位精度问题进行了一些探讨,考查了几个影响目标定位精度的主要因素,并给出了部分计算和测试结果。

This paper discusses several main factors which affect the apparent centre position precision and must be cousidered previously in order to ensure system reasonability and to provide the required angle testing precision of calibration system before the structure size of the simulated RF target is designed.
