摘要

The compact antenna test range (CATR) is one of system for precise antnna 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 plane wave spectrum 9PWS) and Generalized microwqave 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 inverse method (IM) Using inverse method, the antenna and RCS measurement errors can be corrected, an dthe 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.
