摘要

从提高目标距离估计和降低副瓣电平两个方面,提出并研究了两种新的非线性调频雷达信号模型。将所提出的信号模型的性能与目前流行的线性和非线性调频信号模型进行了比较。利用Cramer - Rao下界、主瓣宽度和峰副瓣比对信号模型进行了比较,结果表明所提出的信号模型可以获得更好的距离精度和更小的副瓣。

Novel radar signal models using nonlinear frequency modulation
Two new radar signal models using nonlinear frequency modulation are proposed and investigated with respect to enhancing the target's range estimation and reducing the sidelobe level. The performance of the proposed signal models is compared to the currently popular linear and nonlinear frequency modulation signal models. The Cramer Rao Lower Bound along with main lobe width and the peak to sidelobe ratio are used for comparing the signal models to show that better range accuracy and smaller sidelobes can be achieved with the proposed signal models.
