摘要
直接在系统级测量星上通信系统辐射性能的方法与常规方法（即由分系统测量数据计算出系统数据的方法）相比，有更高的精度。文章介绍的这种方法，在测试系统的构成和软件的编制上，把重点放在用户最关心的指标，如ＥＩＲＰ覆盖等值图，服务区覆盖率，Ｇ／Ｔ值和ＳＦＤ覆盖等值图上。用该方法对中国第三代通信卫星“东方红三号”的有效载荷进行了测试并得到了满意的结果。
method of CAT for radiation performance test on space borne communications system level has been developed. Compared with the conventional method, by which the system performance data are got by calculation of the data gained in subsystems tests, the method described here has got higher accuracy. The test and software was set-up with a focus on getting directly the most important system charactritics,that the users are most interested in,such as EIRP coverage,coverage rale of service zone, G/T and SFD coverage.A test on the payload of DFH-3, the third generation of Chinese communications satellite, was performed and the results of the test were satisfactory.
