现代防空作战中,地对空雷达干扰系统常常会被关注一个问题:能掩护多大RCS的地面目标。针对这一问题,提出了系统可掩护的目标RCS的建模方法。该方法考虑了对作战对象不同体制雷达的干扰压制系数和对不同作战对象的战术要求最小干扰距离。仿真实例分析表明,干扰同一体制机载、弹载雷达时,干扰站配置距离越近可掩护的目标RCS越大;当干扰站配置距离相同时,干扰常规脉冲雷达时可掩护的目标RCS明显大于干扰PD体制雷达时的情形。

In modern air defense operations, how much RCS ground targets can be shielded is a matter of concern of ground-to-air radar interference systems. Aiming at this problem, the modeling method of the target RCS which could be covered by the system was proposed This method took into account the interference suppression coefficient of different combat object radar systems and the minimum interference distance of the tactical requirement of different combat objects The simulation results show that when jamming the same system airborne or missile borne radar, the closer the configuration distance of interference station, the larger the target RCS can be covered. And when the configuration distance of interference station is the same, the target RCS that can be covered when interfering the conventional pulse radar is obviously larger than that of interfering the PD system radar.
