摘要
针对机载相控阵脉冲多普勒雷达的特点,分析了机载预警雷达参数的选取准则与参数间的内在联系.为解决机载预警雷达中脉冲重复频率(MPRF)优化问题,运用简单易用、具有较强的鲁棒性和全局寻优能力的差分进化算法对MPRF进行优化,提出了优化MPRF组的步骤.最后结合最优MPRF组,给出了雷达波形参数设计实例.仿真结果表明,运用该算法所得的最优MPRF组能有效降低机载预警雷达的探测盲区.应用实例验证了机载相控阵多普勒雷达MPRF优化设计与选择方法的有效性与可行性.
Based on the characteristics of the airborne phased-array pulse Doppler radar, this paper analyzes the selection criteria and the internal relation among parameters of airborne early warning radar. In order to solve the optimization problem of MPRF for airborne early warning radar, this paper uses the differential evolution algorithm which is simple and easy to use and with strong robustness and global optimization ability to optimize MPRF, and then proposes the steps of optimizing MPRF group. Finally, combined with the optimal MPRF group,an example of radar waveform parameter design is given. The simulation results show that the optimal MPRF group obtained through this algorithm can effectively reduce the detection dead zone of airborne early warning radar. The application example demonstrates the effectiveness and feasibility of the MPRF optimization design and selection method for airborne phased array Doppler radar.
