| 摘 要： | 为解决基于雷达高度表探测的地形匹配导航系统探测精度不高、易受电子干扰影响而失效、且在跨海飞行时无法导航的难题，设计了一种激光高度计来代替雷达高度表进行地形探测。采用二极管泵浦固体激光器技术设计激光发射装置，输出近红外/蓝绿双波长激光，既可以测量陆地地形高度，又可以穿透海水探测海底地形；并根据激光高度计拟达到的性能指标选择合适的光电探测器，优化设计了光学系统、扫描系统和信号处理系统。所设计的激光高度计具有体积小、重量轻、高重频、探测灵敏度高、抗电磁干扰能力强等特点。

| Abstract: | The terrain matching guidance system equipped with radar altimeter has low detection precision and is susceptible to electromagnetic interference. Moreover, it can not work over the sea. In order to resolve these problems, a scheme of laser altimeter is designed to take the place of the radar altimeter. The technology of diode-pumped solid-state laser is adopted to design laser transmitter, outputting infrared/blue-green dual-wavelength laser. The altimeter with dual-wavelength output can detect both the land terrain and the seabed terrain. To promote the performance of the laser altimeter, the detectors are selected carefully, and the optics system, the scanning system and the signal processing system are designed optimally. The designed laser altimeter features small size, light weight, |
