本文应用效率准则,首先分析选取典型的电磁干扰环境并将其分类,为雷达系统的使用环境提供一个标准。 其次,根据雷达分系统中受压制型干扰影响的战术性能指标给出雷达分系统抗干扰性能指标体系,以便衡量雷达分系统的抗干扰能力。然后给出抗干扰指标的临界值体系的概念及建立方法,并由此给出雷达分系统抗压制型干扰的评价因子及雷达系统抗压制型干扰的评价因子——有效度的概念及算法,完成对机载火控雷达抗压制型干扰性能的评估。 This paper applies the efficiency criterion, first of all, analyzes and classifies the typical electromagnetic interference environment and provides a standard for the use environment of the radar system. Secondly, the anti-jamming performance index system of the radar subsystem is given according to the tactical performance index influenced by the suppression interference in the radar subsystem to measure the anti-interference ability of the radar subsystem. Then, the concept of critical value system of anti-jamming index and its establishment method are given. And then the evaluation factor of anti-jamming of radar system and the evaluation factor of anti-jamming of radar system are given. Algorithm, to complete the airborne fire control radar compression suppression performance assessment.
