本文叙述了 CO_2激光雷达的特点及其在侦测、火控、导弹制导、巡航导弹、遥感等方面的应用。一、前言近些年来,人们发现 CO_2激光器在雷达系统上有很广阔的应用前景。CO_2激光器的功率和效率高;光束质量好,光束宽度接近于衍射极限,时间和空间的相干性好,因而对光学系统的准直性要求不苛刻,并且可以应用各种调制方法调制波形;CO_2激光器发射的红外激光透过霾、雾或战场烟雾的性能好,并对眼睛安全,与目前战场上广泛使用的8～14微米热成象仪的匹配性能好,并可以使用高灵敏度的外差探测。这些特点使得 CO_2激光器成为激光雷达理想的光源。
This paper describes the characteristics of CO2 laser radar and its application in detection, fire control, missile guidance, cruise missiles and remote sensing. I. Introduction In recent years, it has been found that CO2 laser has a very broad application prospect in the radar system. CO 2 laser has the advantages of high power and high efficiency, good beam quality, beam width close to the diffraction limit, good temporal and spatial coherence, and thus the collimation of the optical system is not demanding, and various modulation methods can be used to modulate the waveform. CO_2 The infrared laser emitted by the laser transmits haze, fog or battlefield smoke with good performance and is eye-safe. It matches well with the widely used 8-14 micron thermal imager on the battlefield and can use high-sensitivity heterodyne Probe. These characteristics make CO 2 laser the ideal light source for LIDAR.
