Aiming at the issues of plenty of complex test equipment, and organization and implementation difficulty in radar anti-jamming performance evaluation under the background of electronic warfare in information age, a novel test method based on the calculation model of radar anti-jamming performance specifications and semi-physical simulation system is proposed. The inherent relation between the key specifications, such as burn-through range and effective jamming sector, and the radar performance parameters is analyzed. In order to meet the requirements of miniaturization, integralization and intelligentization in anti-jamming test, a new design scheme of radar ECM integrated signal generation system （REISGS） is proposed The system adopts advanced DSP technique, interface circuit design and terminal display ＆ control technique to realize the state data acquisition, target echo simulation and flexible setting of complex ECM scenarios. A certain radar was used as example to carry out the anti-jamming performance test in the combat scenarios generated with the REISGS. The experiment tests of burn-through range and range gate pull off （RGPO） were conducted to verify the reasonability and effectiveness of the test system. This study results provide an important support for achieving the radar performance test and anti-jamming strategy making in complex battlefield environment.
