Therefore, the active ware of microwave communication-SAR ( Synthetic Aperture Radar), which is timely, independent of illumination and high rate repeating coverage, has been considered as one of the most important information sources of agricultural inspection in these areas. 因此,全天时、全天候、不依赖于光照条件,具有高重复覆盖率的主动微波遥感器-合成孔径雷达(SAR)被认为是这些地区农作物监测的最重要的信息源之一。
A study on the bistatic radar detection system based on non-cooperative illumination 基于外照射源的双基地雷达探测系统研究
Application of high power semiconductor laser were summarized in some fields such as laser communication, laser guidance, laser radar, laser fuse, laser range-finding, laser night vision and illumination, laser simulating weapon and military fiber peg-top, etc. 简要阐述了高功率半导体激光器在激光通信、激光制导、激光雷达、激光引信、激光测距、激光夜视与照明、激光模拟武器以及军用光纤陀螺等领域的应用。
When a target of given elevation stays out of the desired radar search zone, a specific beam needs to be assigned to the given elevation so as to make illumination of that target. 指定仰角目标如果不在雷达指定搜索范围,需要抽调指定波位到指定仰角对目标进行照射。
The two models for the LRG imaging system which are a simple illumination model and the pixel related laser radar model are presented. The relation between the range and the laser power is simulated adopting the simple illumination model. 建立了激光距离选通成像系统两种模型,即简单照明模型和基于像素的激光雷达模型。
