| 摘 要： | 给出了LFMCW雷达信号的多周期模糊函数,并与单周期信号进行了比较。讨论了在单周期和多周期的模糊函数联系,沿主轴切割模糊函数的性质和体积有限方面上两者特征的差别。仿真结果表明,增大周期可提高多普勒分辩力,但不能改善时延分辩力。

| Abstract: | The multi-period ambiguity function of LFMCW radar signal is given, and compared with single-period ambiguity function. Some properties of difference with single-period is discussed, these properties include the multiple-single period PAF,cut along the principal axes and volume limitation. The computer simulation showed that Doppler resolution being higher , but delay resolution is not improved as number of periods increases. |
