摘要

小型天线试验场(CATR)是精密天线和RCS测量系统之一。CATR的主要特征是静区内的场幅值纹波和相位纹波。本文利用平面波频谱(PWS)和广义微波网络，推导了天线(或RCS)测量精度与CATR安静区质量之间的定量关系。这种方法被称为逆方法(IM)。利用逆方法可以对天线和RCS测量误差进行校正，提高测量精度。计算结果表明，在相同条件下，相当区波纹带来的RCS测量误差大于天线测量误差。

Inverse method for analyzing the antenna and RCS measurement precision

The compact antenna test range (CATR) is one of system for precise antenna and RCS measurement. The main characters of CATR are the field magnitude ripple and the phase ripple in the quite zone. In this paper, using the plane wave spectrum (PWS) and generalized microwave network, we have deduced the quantitative relationship between the antenna (or RCS) measurement precision and the quality of CATR quiet zone. This method is called the inverse method (IM). Using the inverse method, the antenna and RCS measurement errors can be corrected, and the measurement precision can be improved. According to the calculation result, the RCS measurement errors brought over by the ripples in quite zone is larger than the antenna measurement errors under the same conditions.
