对抗有源干扰的雷达探测范围修正模型与分析

Model modification and analysis of radar detection range for anti-jamming

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，可以简便灵活地应用，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了基础。最后通过仿真实验说明了上述模型的可用性。

Abstract:

Active jamming was one of the most important menaces for radars, and the radar detection range was the groundwork 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 validity of the modified model.
