外场RCS测量精度模型及其工程化估算

摘要

In this paper,the source and size of error causing the RCS measurement are analyzed and calculated using the theory of random process error analysis based on the principle of RCS measurement. The estimation model of RCS measure⁃ment accuracy over wide frequency band is constructed.The model and the estimation method provide a reliable basis to de⁃sign and control accuracy index for RCS radar and accuracy estimation of RCS radar equipment.%基于RCS测量原理，运用随机过程误差分析理论，在工程实践层面，对造成RCS测量误差的来源、大小等进行了分析和计算统计，构建了宽频段RCS测量精度估算模型，为RCS测量雷达精度指标设计和控制以及在用RCS雷测设备精度估算提供了可靠依据。
