摘　　要：为了提高红外激光雷达测距系统的测量精度和可靠性，设计并实现了基于高速模数转换器和数字信号处理（DSP）技术的DSP鉴相器。使激光雷达测距系统在2km测程内的测量精度达到3mm。In this paper,the design and realization of a new generation of lidar distance measurernent system are Dresented. A DSP (Digital Signal Process) phase detector based on high speed analog-to-digital converter and DSP technique has been designed,in order to irnprove the precision and reliability of infra-red lidar distance measurement system. As a result,the lidar distance measurement system we have developed with a DSP phase detector has a precision of 3 millimeters in the measuring range of 2 kilometers.
