摘要
针对准连续波雷达中的距离遮挡问题,研究了非脉间和脉间码型捷变的波形优化方法。在定义距离遮挡率函数的基础上,给出了非脉间码型捷变的多相码整体优化惩罚函数和基于模拟退火搜索的非脉间码型捷变的多相码整体优化方法;考虑到目标运动带来距离门跨越的问题,给出了脉间码型捷变的距离门匹配多相码优化准则和优化方法。仿真结果表明了该波形优化设计方法的有效性。
To solve the problem of range eclipse in quasi-continuous wave （CW） radar, waveform optimization methods for radars with and without intra-pulse code agility are discussed. Based on the definition of range eclipse ratio function, penalty function for optimizing waveform for the radar without intra-pulse code agility is given and the corresponding poly-phase coded signal optimization method based on simulated annealing is proposed. Considering the is- sue that a target may cross multiple range gates, a range gate matched waveform optimization method for the radar with intra-pulse code agility is proposed. Simulation results show that these methods are feasible and effective.
