The electrical performance parameters of radome include transmission and bore-sight error. The composition of the testing system is described in this paper. The core algorithm of dynamic null-seeking is used according to the test principle of electrical performance parameters. The system software takes VS2010 as development platform and is developed with C# programming language. The key technology of the system is analyzed. The simultaneous measurement of transmission and bore-sight error is realized. The test results show that the repetition test accuracy of transmission is less than 2?? and the repetition test accuracy of boresight error is 0. 26′(RMS). Compared with the method of static null-seeking, test efficiency has been improved many times. This system has important reference significance for electrical performance test of radome.
