Seen from the latest local war, the air-lined radar opposition has become a key instrument through out the war. It effects on the process and results. The air-lined radar opposition is not only a guarantee of the war, but also a military hit force. So the study of air-lined radar opposition is good for the victory of the war. The paper has concluded and created the criteria of the radar, constructed the model of foil opposition and proved that the capability had decreased apparently. The paper has studied the air-lined radar electronic opposed simulation system, simulated the platform of air-lined radar electronic opposed system. The system is a good tool to train the talents of electronic opposition.
