| 摘要: |
| 提出了一种基于目标特性的雷达探测能力评估模型。该模型在给定的虚警概率和Swerling模型等条件下，建立起了发现概率与最大探测距离的数学关系。而考虑到雷达系统损耗和传播因子F对距离评估的影响，将这些因素统一概括成修正因子M定量描述。可通过Albersheim方程或Shnidman方程，推导出一个计算M因子的算法，再用M因子对最大探测距离进行修正得到实际距离，实现雷达距离以概率形式而非简单数字的完整描述。最后，以发现概率为指标对雷达网的威胁进行了评估。 |

| Abstract: |
| A radar detection capability evaluation model based on target characteristics is proposed. The model establishes the mathematical relationship between the detection probability and the maximum detection distance under the given conditions of false alarm probability and Swerling model. Taking into account the impact of radar system loss and propagation factor F on distance assessment，these factors are uniformly summarized into a quantitative description of the correction factor M. An algorithm for calculating the factor M can be derived from the Albersheim equation or the Shnidman equation，and the maximum detection distance can be corrected by the factor M to obtain the actual distance，so that the radar distance can be completely described by probability rather than simple numbers. Finally，the threat of the radar network is evaluated by detection probability. |
