摘要
机载预警雷达与地面预警雷达联合组网技术的迅速发展使得飞行器突防变得越来越困难。在考虑飞行器机动性约束的前提下提出了一种"隐身"低空突防航迹规划方法,该航迹规划一方面利用机载预警雷达的多普勒盲区实现相对于机载预警雷达的"隐身",另一方面低空飞行可以有效规避地面预警雷达的探测,该航迹大大提高了飞行器突防的成功率。考虑到机载预警雷达的位置信息无法事先获取,给出了固定时间步长的搜索方法求解该规划模型。仿真实验结果证明了提出的机动性约束下的隐身低空突防航迹规划方法的正确性。
With the rapid development of airborne early warning （AEW） radar and ground early warning radar combined networking technology, the penetration of aircraft becomes harder and harder With the consideration of flexibility restraint, the model for the path planning of stealthy low-altitude penetration is established. The path planning is invisible relative to AEW radar using Doppler blind zone and low-altitude flight can avoid the detection of ground early warning radar. The route greatly increases the success rate of the aircraft＇ s penetration. Considering the position information of AEW radar cannot be obtained in advance, and a fixed-time-step searching method is adopted to solve the model. The simulation results demonstrate the correctness of the developed method for path planning of stealthy low-altitudepenetration under flexibility restraint.
