| Abstract: | According to theory of electromagnetic scaled model, this paper introduces the theory and conditions of EMC ship model prediction, and deduces the relations of the scaled ratio to inducting voltage on the antenna terminal and antenna coupling. The antenna radiation pattern and antenna coupling or isolation as well as near electric field strength are measured by using anechoic chamber as the test site of ship model prediction. Through the comparison of theory computation with test results, it is concluded that it is correct and feasible to adopt this kind of method for determining communication antenna optimization arrangements and realizing the EME distribution. By using automatic test system based on virtual instrument software platform it is achieved to develop EMC ship model prediction in the anechoic chamber. |
