摘要
舰载雷达效能不同于舰载雷达的一般性能,它是一个建立在舰载雷达性能基础之上的综合概念。文中从系统的观点出发,考虑了现代高技术条件下海上局部战争中舰载雷达面临的电子干扰环境的复杂性,以研究集多种体制于一身的舰载雷达在综合干扰条件下的效能问题为例,首先介绍了干扰条件下舰载雷达效能的评估准则,给出了干扰条件下舰载雷达效能评估的数学模型;之后详细推导出该数学模型中关键的舰载雷达发现概率的计算方法以及雷达接收机输入信噪比等参数在干扰条件下的计算方法。
The shipboard radar＇s efficacy is different from its common performance,but it is a generalized concept based on shipboard radar performance. Starting from the point of view of system, the complexity of the electronic jamming environment which the shipboard radar can meet under modern hi-tech local sea batties, must be considered. Taking the shipboard radar efficacy under combined jamming for example, the principle and the mathematic model of efficacy assessment of shipboard radar under jamming are presented. And the calculation of detection probability and signal-noise ratio of the shipboard radar, which are the key param- eters in the mathematic model, is given in detail.
