Abstract:

It is one of the most important means of acquiring the object’s radar signature to measure the object directly in the millimeter wave compact antenna test range anechoic chamber system(MMW CATR ACS). The MMW CATR ACS is a complicated system engineering with great difficulties in design, construction, test and application. The constraints between type, total size and manufacture error of the CATR reflector are mainly by such figures as frequency band, quiet zone, background noise level, system sensitivity and dynamic range, the constraints between bandwidth, sensitivity, dynamic range, instrument choice by measurement frequency. The qualitative and quantitive models are also founded for the MMW CATR ACS design. The research will help to design, evaluate and utilize the system.
