现代战争电磁环境日益复杂,急需有效手段计算和评估传感器的实际性能指标。针对雷达复杂探测环境,深入分析了有源压制性干扰等影响雷达威力范围的诸要素。进而,联合现有噪声条件下雷达探测距离和干扰条件下雷达自卫距离计算方法,推导得到了修正的有源压制干扰下雷达探测距离计算新方法。新方法物理含义明确,计算简明,同时避免了现有自卫距离计算的不合理性。最后,基于实际背景的数值仿真结果证明了该方法的有效性。

The electron magnetic environment becomes more and more complicated.It is urgent to propose effective method to calculate,analyze and evaluate the real performance of modern sensors.For the complicated radar detection environment,this paper analyzes the factors affecting radar detection range under the condition of active blanket jamming.Based on the maximum detection range under noise background and the self-defense range under jamming environment,we derive a modified method for radar detection range calculation.The proposed method has an explicit physical meanings and simple calculation process.It can overcome some irrational cases for the existing self-defense range calculation.Finally,some real simulation results under a real background are provided to demonstrate the effectiveness of the proposed method.
