摘要
正交线性调频信号是MIMO雷达正交波形设计中最基本的一种波形.主要阐述了正交线性调频信号的模型和模糊函数,分析了峰值旁瓣的大小、互相关峰值及其出现的位置.使用线性调频信号进行了目标位置检测,通过Matlab仿真验证了理论分析的结果.
OFD-LFM（orthogonal frequency division-linear frequency modulation） signal is a kind of waveformwhich basically used in MIMO radar. In this paper, the model of OFD-LFM signals is summed up and the ambigui-ty function of OFD-LFM signals is analyzed. The size of the peak sidelobe, thelocation and level of the cross-corre-lation peaks are analyzed. By using the OFD-LFM signals the target position are estimated. Matlab simulations aredone, which verify the validity of the theoretical results.
