DDS-based Chirped Amplitude Modulation Technique Applied in Laser Radar

对传统调频雷达测距原理进行了改造,提出了一种适用于激光雷达系统的啁啾调幅技术。该技术在低成本,短距离的激光雷达应用中性能优势明显。详细介绍了啁啾调幅激光雷达的工作原理,完成了基于DDS技术的啁啾信号生成及处理模块的设计。

A chirped amplitude modulation technique is introduced to apply in the laser radar system which is practically adapted from the frequency modulation radar ranging principles. This technique performs very well in low-cost, short-range laser radar applications. The principle of the chirped amplitude modulation laser radar is discussed here, and the DDS-based chirp waveform generation and processing are also designed.
