Abstract

The nonlinear of the frequency modulation in linear frequency modulation (LFM) lidar seriously affects the accuracy of range and velocity. We describe the influence of nonlinear of the frequency modulation on the accuracy. The frequency-domain analysis of heterodyne signal is used to deduce the linearity requirement for LFM lidar.
