Abstract
Synthetic aperture ladar is an important way to realize computational imaging.Firstly, a multi-channel inverse synthetic aperture ladar (ISAL) prototype, imaging detection experiment and signal processing method are introduced. Then, the composition of the prototype system and key technical solutions are described. Moreover, the experimental results of imaging detection of moving vehicle targets on ground are given by a coherent ladar prototype based on a one-transmit multiple-receive pulse system and an optical path with all fiber. Finally, under the wide view field conditions of expanding transmitting and receiving beams, the high-resolution imaging capabilities of multi-channel ISAL and the effectiveness of the along-track interferometry motion compensation imaging method are verified.
