With differential absorption laser radar as background, the key techniques related in designing real-time monitor and control system based on WDM (Wavelength Division Multiplexing) are studied.
以差分吸收激光雷达为背景，对基于WDM的实时监测控制系统的设计中涉及的关键技术进行研究。
Such a single point figure permits at best a detection range estimate for a known radar operating at the specified wavelength and aspect.
这种单个点阵图所表示的最大范围只是一个已知雷达在规定波长和位面的探测距离。
Owing to the decametric wavelength, the angular resolution of High Frequency Surface Wave OTH Radar (HF SWOTHR) is usually coarse especially when dimensions of antenna array are restricted.
由于工作在高频段，高频地波超视距雷达的角分辨力较差，尤其是当阵长受限时。
