针对基于射频(RF)隐身需求的机载雷达目标搜索问题进行了研究。通过分析实际作战中射频辐射面临的截获威胁,提出了一种基于联合截获威胁的射频隐身性能表征方法,并给出了具体的值估算方法;对机载雷达搜索任务中辐射参数的优化问题进行了建模,并采用优化算法对目标函数进行求解。通过分析典型情景下解集的分布特点,给出了从最优解集中选取最终解的方法。结果表明,提出的射频隐身性能表征方法能更好地反映截获实现过程的多域需求,提出的雷达搜索方法能够在保证探测性能的同时,提高射频隐身性能和搜索速度,能够为相控阵雷达搜索任务中参数的优化控制提供方法和依据。

The radar target search problems based on radio frequency (RF) stealth is researched in the paper. By analyzing the intercept threats of actual battlefield faced by radio-frequency radiation, a new characterization method based on joint intercepted threats of RF stealth performance is proposed, and the value estimation methods is also given; A model of parameter optimization problem for airborne radar search parameters is built, and using optimization algorithms to solve the objective functions. By analyzing the distribution characterics of the solution set of typical scenario, the method of selecting final solution is given from optimal solution set. The result shows that, the RF stealth characterization method proposed is better to reflect the multi-domain requirement of intercepted, the radar search method can improve the RF stealth performance and the search speed while assuring the detection performance, and provide methods and basis for parameter optimization and control in phased array radar search tasks.
