Abstract
Compared with single-pulse detecting laser radar, the Chirp AM (Amplitude modulation) lidar with advantages of higher range resolution, higher precision, and stronger anti-jamming ability, has a wide application prospect in laser terminal guidance, terrain mapping and other fields. This paper focuses on design and implement of 9×9 fiber array processing of chirp AM lidar, mainly including 9×9 fiber receiving array, 81-channel broad band down conversion and 81-channel signal processing. The detection experiment in which range resolution is 0.249m and angular resolution is 0.6mrad is done, which lays a foundation for development and engineering application of chirp AM lidar.
