高分辨率雷达 meaning in English
high resolution radar
Examples
- With the development of sar ( synthetic aperture radar ) technology , a large amount of images are made by space - borne and airborne sar , it ' s important to use atr technology in sar images analysis and advance the level of target recognition of high - resolution radar
合成孔径雷达( sar )技术不断发展，星载与机载sar成像数量极大，在sar图像分析中应用atr技术，加强对高分辨率雷达图像目标的识别分类具有重要价值。 - Targets in the radar ppi have the main property of the little area , a few targets and irregular change of grey . so it is difficulty to detect and track the target . the study of the radar ppi is very few inland and abroad . with the development and implement of high resolution radar and high resolution raster display , target _ tracking and detecitng based on the radar ppi will be feasible . it ' s great excellence is to increase time accumulation compare with the detecting techenicial of the traditional radar
雷达ppi中目标的特点是面积小，目标或可能的目标多，灰度、形状变化无明显规律，所以检测和跟踪目标比较困难。基于雷达ppi的研究国内外甚少，随着高分辨率雷达和高分辨光栅显示器的发展，基于ppi的雷达目标检测和跟踪成为可能。与传统的雷达目标检测技术相比，其潜在的优势在于大大增加了信号的时间积累，因此有可能提高检测性能。 - Abstract : it is essential to research radar clutter with non - gaussian spectrum and non - r ayleigh distribution in modern radar design . based on spherically invariant rando m process ( sirp ) , this paper applies a new algorithm to model the clutter with k d istribution in amplitude and any power density spectrum . at last it is proved tha t thi s method is correct and applicable with real simulative clutter and statistical detection result
文摘:研究并模拟具有非瑞利幅度分布和非高斯功率谱的雷达杂波是现代雷达信号处理中的一个重要的研究课题.文中基于球不变随机过程( sirp )的建模方法，针对实地采集的幅度满足k分布并具有有理功率谱的高分辨率雷达杂波，运用现代谱估计算法对其进行建模和仿真，并以模拟杂波与实际杂波的数据对比和统计检验的结果对该方法进行了验证
