合成孔径雷达就是利用雷达与目标的相对运动把尺寸较小的真实天线孔径用数据处理的方法合成一较大的等效天线孔径的雷达。合成孔径雷达的特点是分辨率高,能全天候工作,能有效地识别伪装和穿透掩盖物。 合成孔径雷达主要用于航空测量、航空遥感、卫星海洋观测、航天侦察、图像匹配制导等。它能发现隐蔽和伪装的目标,如识别伪装的导弹地下发射井、
Synthetic aperture radar is the use of radar and target relative motion to the smaller size of the real antenna aperture data processing method of synthesis of a larger equivalent antenna aperture radar. Synthetic aperture radar is characterized by high resolution, can work around the clock, can effectively identify camouflage and penetrate the cover. Synthetic aperture radar is mainly used for aviation surveying, aviation remote sensing, satellite ocean observation, space reconnaissance, image matching guidance. It can detect hidden and disguised targets, such as identifying camouflaged missile subsurface silos,
