针对外辐射源雷达探测范围采用隐式表达,常用的网格计算法计算繁复、不直观,不便于无源雷达探测使用的问题,文中在深入分析外辐射源雷达探测覆盖特性的基础上推导出了一种快速计算外辐射源雷达探测范围的方法,将外辐射源雷达探测范围隐式表达转换为显式表达式,计算简单,方便应用。该方法仅需要给定系统参数、雷达基线长度,即可方便获得外辐射源雷达探测范围,从而极大方便了雷达用户快速掌握雷达威力。仿真验证表明,文中方法与经典基于等信噪比曲线的方法计算结果完全一致,同时也证明了方法的有效性和科学性。

The detection range of passive radar adopts implicit expression, and the common grid calculation method is used for analysis. The disadvantage is that the calculation is complicated and not intuitive, and it is not convenient for these users of this kind of radar. To address the problem, a method to rapidly calculate the detection range of passive radar is deduced based on the in-depth analysis of the characteristic of its detection coverage. The proposed method makes the implicit expression of its detection range into explicit one, which the calculation is simple and its application is convenient. The simulation shows that the results of the radar detection range by the proposed method is the same as the one calculated by the classical signal noise ratio curve, which proves the proposed method is valid and effective. The method only requires a given system parameter and radar baseline length, which can easily obtain the detection range of the passive radar, so as to greatly facilitate the radar user’s rapid acquisition of radar power.
