摘要
在海上编队作战中，噪声干扰是对敌方舰载远程搜索警戒雷达进行压制的一种有效干扰手段。为了能够快速简便地对雷达干扰效能做出评估，在对雷达检测概率特性分析的基础上，通过雷达干扰的空间能量方程导出在噪声干扰条件下雷达发现概率与距离之间的关系式。将雷达发现概率的下降程度作为干扰效能的评估因子，通过MATLAB仿真对干扰效能进行定量分析，得出在某一作战态势下的最小干扰距离以及雷达最大作用距离，结果明确合理。
Noise jamming is an effective method to suppress shipborne surface and scanning warning radar in fleet operation on the sea. In order to rapidly and simply evaluate the radar jamming efficiency, the relationship between range and discovery probability is got through the space-energy formulas of radar jamming based on the analysis of the characteristic of radar detecting probability. The decrease degree of discovery probability is considered as the factor to evaluate jamming efficiency, the jamming efficiency is quantitatively analyzed through MATLAB simulation, the minimum jamming range and the maximum detection range is got in a given operational situation, the result is clear and reasonable.
