摘要
报道了一个正弦相位调制的大视场机载直视合成孔径激光成像雷达。在室外3.8km进行了视场扫描并获得了高分辨率合成孔径成像。同时给出了该机载直视合成孔径激光成像雷达的3km飞行试验结果,获得了高质量大视场图像,其成像视场提高了一个量级,达到了4.8mrad。
Large field of view airborne down-looking synthetic aperture imaging ladar with sine phase modulation is reported. The high resolution and high quality synthetic aperture imaging is realized at target distance of 3.8 km outdoors. Then the airborne down-looking synthetic aperture imaging ladar is used for flight demonstration. The height of the flight is 3 km. High quality and large field of view is achieved. The field of view is enhanced by over an order of magnitude, which is up to 4.8 mrad.
