Abstract
In order to resolve the problem of echo signal threshold detection about LFMCW lidar system, a new signal threshold detection method based on the constant false alarm rate(CFAR) detecting technology is put forward. This method constructed the CFAR detection model from the analysis about the noise’s statistics characteristic in frequency domain, and then analyzed the relation between the false alarm rate and threshold, at last contrasted CFAR threshold with constant threshold under the condition that the noise intensity changes by simulating technique. The simulated experiment result indicates, the CFAR detecting technology applies to an echo signal threshold detecting is able to ensure that the false alarm rate size is constant invariable when the threshold value follows the noise intensity changes, thereby this method is not only improved the lidar’s acclimatization, but also enhanced the systematic detecting function of LFMCW lidar effectively.
