中文摘要：

为了提高评估跳频通信系统抗干扰能力的准确性，对典型的灰关联评估方法进行了改进，设计了一种新的评估方法。该方法在建立指标体系的基础上，根据指标对抗干扰能力的影响趋势的不同，采用多种方法计算不同指标的灰关联度系数，另外根据指标对抗干扰能力的影响程度，用一种混合聚类法实现灰关联度信息的合成。对该方法进行了仿真和验估，结果表明，该方法充分考虑了评估对象的特殊性以及指标的多样性，能够避免误判现像，提高评估准确性。

英文摘要：

In order to improve the accuracy of anti-jamming capacity evaluation of a hopping frequency communication system, a new evaluation method was proposed based on the improvement of the classical evaluation method using grey relation analysis. Under the index system, the new method utilizes several means to calculate the grey relation ratio of different indices according to the difference of indices＇ influential tendencies to the anti-jamming capacity On the other hand, it uses a hybrid clustering algorithm to synthesize relation information according to the influ- ences of indices on the anti-jamming capacity. The method was tesified by simulation, and the results show that it fully considers the specific characteristics of evaluation targets and the diversity of indices, so it can prevent wrong judgments and have a higher evaluation accuracy.
