摘要
主要研究了小型化表面波雷达阵列发射天线的波形特性。建立发射信号模型和波形优化目标函数,采用模拟退火算法优化求解目标函数。针对优化的跳频码序列进行仿真实验,得到仿真结果。对不同波形的自相关函数和模糊函数特性进行了研究和比较。仿真结果表明:所设计的波形较其他波形具有较优的自相关特性。研究结果可为小型化高频地波雷达的波形设计提供一种可行的方法和思路。
The waveform characteristics of a miniaturized surface wave radar array transmitting antenna are studied.The transmitting signal model and waveform optimization objective function were established,and the simulated annealing algorithm was used to optimize the objective function.Simulation experiments were performed on the optimized frequency-hopping code sequence,and the simulation results were obtained.The characteristics of autocorrelation function and ambiguity function of different waveforms were studied and compared.Simulation results show that the designed waveforms have better autocorrelation characteristics than other waveforms.The results can provide a feasible method and idea for the waveform design of miniaturized high frequency ground wave radar.
