摘　　要：简述了新型静态偏振风成像干涉仪的原理,推导出一般情况下系统的Jones矩阵.在此基础上计算了系统中各偏振器件重要参数在非理想情况下对风速和温度探测结果的影响.利用计算机模拟对探测误差进行了分析,并按照系统精度要求从理论上提出了各重要参数的误差容限.该研究为新型静态偏振风成像干涉仪的研制、定标及后期数据处理提供了理论依据.The principle of a novel static polarization wind imaging interferometer is described,and the Jones matrix of the system is derived in general case. The theoretical measurement errors of the wind and temperature,introduced by some important parameter errors of all the polarization components in the system,is calculated and analyzed by computer simulation. The tolerances of the parameters are proposed according to accuracy of the system. The study provides a theoretical basis and practical guidance for the development,calibration and data post-processing of the novel static polarization wind imaging interferometer.
