Abstract: To wholly assess the anti-interference of warning radar system, the comparatively integrated and feasible test-assessing system on anti-interference performance is introduced. Firstly, the system of assessing indexes on anti-interference ability is constructed. A series of tactics and technique quantified indexes is defined. Secondly, the simulated test method is designed, including how to deploy testing position, how to change and calibrate testing parameters and so on. Lastly, based on the assessed target, the corresponding assessing method is proposed.
