| Abstract: | This paper proposes a new linearity correcting method of LFMCF, which can be easily realized in engineering based on traditional delay PLL. The correcting principle is described in detail. And the computer simulation of this method is performed. The results show that the linearity of the frequency-swept generator is raised, and the practical requirements of high distance resolution of LFMCW radar can be satisfied. |
