摘　　要：针对传统评价方法在双基地雷达电子干扰效能研究中的弊端,提出了基于R站不确定的双基地雷达电子干扰效能评估方法。该方法基于"对双基地有效干扰需对双基地可行配置区域内所有具有威胁价值的R站布站点均能保持有效作用"这一假设,选取"有效干扰比"作为指标,估算对未知R站的干扰可能性,并给出了计算所需的相关模型;评估实例验证了方法的可行性和合理性,得出了一些有意义的结论。An efficiency evaluation method of electronic countermeasure （ECM） against bistatic radar based on uncertain receiver station is proposed, so as to overcome the disadvantage of traditional evaluation method. Based on a precondition that the bistatie radar will be interfered only if each menace receiver is jammed effectively, an efficiency index called efficient jamming ratio is giv- en, which can calculate probability of efficient jamming against unknown receiver. Then, some correlative models are given. Final- ly, evaluation example validates the method and draws some useful conclusion.
