摘　　要：有源干扰是雷达电子对抗中最重要的威胁之一,而雷达探测范围是衡量抗干扰性能的基础。为便于在干扰环境中计算雷达探测范围、分析抗干扰性能,在对雷达探测范围理论计算和实际抗干扰措施分析的基础上,给出简化通用的雷达探测范围修正计算模型。该模型仅需计算一系列修正因子,应用简便灵活,并且能够体现对抗干扰的探测范围动态变化,为评估与改进抗干扰性能提供支持。最后通过仿真实验验证了该模型的有效性。Active jamming was one of the most important menaces for radars, and the radar detection range was the basis for evaluation of anti-jamming. Based on the analysis of theoretical computation and practical anti-jamming measures, a modified mathematical model for calculating the radar detection range in jamming environment was proposed. The simplified model only needed the calculation of a few modification coefficients, so it was convenient for application. The model could also explain the dynamic change of radar detection range under different anti-jamming measures, thus it was helpful for the evaluation and improvement of the anti-jamming performance. The simulations showed the validity of the modified model.
