在虚警概率恒定、检测概率可变的假设条件下，系统研究了不同目标类型之间的雷达探测距离换算问题，推导出一套较为完整、且便于雷达装备型号论证、作战效能评估以及部署优化等实际工程应用的换算公式。误差分析表明，推导出的距离换算公式的最大点误差小于，完全满足实际工程应用对探测距离估算精度的要求。

In this paper, we research in the problems of radar detection range conversion between different types of targets systemically under the conditions of constant false - alarm probability and alterable detection probability, then derivate a series relatively self-contained conversion formulas which is convenient for civil engineering application such as radar equipment argumentation, force effectiveness evaluation and optimum deployment and etc. The error analysis indicate that the max point error of range conversion formulas is under 3%, which satisfy to the evaluation of detection range in civil engineering application completely.
