雷达目标特性的毫米波紧缩场测量方法

紧缩场暗室测量系统是获取雷达目标特征信号的重要技术手段，是复杂的系统工程，设计、施工、测试和应用难度大。本文主要分析了测量频段、静区质量、背景噪声电平、灵敏度和动态范围等指标与反射面类型选择、总体尺寸设计、制造安装精度的约束关系，以及与电磁波收发与测量设备的测量频率与带宽、灵敏度与动态范围、设备选型与集成的约束关系，建立了定性/定量分析模型，为该类系统的设计、选型与应用提供技术指导

MMW CATR measurement for target radar signature

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.
