Based on the unascertained mathematical theory and with electronic countermeasures taken into consideration, a study is made on the evaluation index system and measuring methods, and on how to make identification and sequencing. An evaluation model of jamming effect on radar is set up based on the unascertained effect measurement. The model has been employed in the analysis of a case of active jamming and has been proved successful. This model is perfect, and the evaluating result is reasonable, with a high resolving power. It is suitable for evaluating the jamming effect on radar.\;
