中文摘要：

雷达辐射源威胁等级判定是电子对抗领域的一个重要研究课题，干扰资源的分配以等级判定作为基础。快速、高效和准确地判断出众多目标的威胁程度，成为亟待解决的问题。利用目标权重的层次分析法，确定了威胁因子的权重，提出和建立了一种计算辐射源威胁等级的方法。实例说明，该方法是可行、有效的，为威胁等级的判断提供了一种新的途径。

英文摘要：

Assessment of radar radiant point menace is an important investigative problem in elec- tronic countermeasures. As the allocation jamming resources is based on menace grade. How to assess the menace grade of air attack targets quickly and exactly has become an urgent problem to be solved. By u- sing target power scale＇ s method of arrangement analyzing, menace genes＇ power scales is ascertained. A new method of the account radar radiant points＇ menace grade is put forward. The example given in the end shows the practicability and effect of this method, which provides a new approach for the assess- ment of menace grade.
