结合对雷达抗干扰品质因素（ＱＥＣＣＭ）的分析，给出了一种新的干扰效果评估准则一干扰效果因素（ＱＥＣＭ），并对ＱＥＣＭ进行了定义。随后，本文讨论了ＱＥＣＭ与雷达其它工作性能指标的关系．验证了它作为一种干扰效果评估准则的合理性及有效性。

By the means of analysising radar anti-jamming quality factor (QECCM), we givea new evaluation rule named jamming effect factor (QECM)for jamming effects on a radar, and defineQECM. Then we study relations betwwen QECM and radar working performance index, validate itsrationality and effectualness as a kind of evaluation rule for radar jamming.
