摘要
为适应当前装备更新换代, 更好发挥作战效能, 从雷达应用的角度研究了空战中有源干扰条件下的功率管理措施。以实训数据为基础, 采用数值模拟方法, 分析机载雷达功率管理对电子战侦收的影响, 得出雷达“隐身”距离、雷达最大探测距离以及电子战最大侦收距离三者之间呈等比关系。在此基础上对比分析了雷达“隐身”距离与“烧穿”距离之间的关系, 得出本机雷达具备明显信号隐身优势时应尽早采取功率控制措施, 在均势状态下慎用甚至不用功率管理, 以避免雷达同干扰对抗过程中丧失能量优势, 导致抗干扰能力显著降低。研究结果为机载雷达使用提供一定的参考依据。
Abstract
In order to be more adaptable to the upgrading of airborne equipment and enhance the capability of the fighters, the power management of airborne radar under active interference condition in air-to-air combat is researched from the pilots’ point of view. The effect of radar power management on electronic warfare interception is analyzed firstly. According to the numerical simulation results based on flight training data, the mismatch range of target Electronic Support Measure(ESM), the tracking range of the radar and the interception range by the target ESM compose geometric series. Then the relation between the mismatch range and burn through range is discussed. It is concluded that power manage measures should be taken on condition that the radar is superior to the target ESM obviously, otherwise the measures should not be taken in case of radar losing energy advantages over the target interference.
