Abstract :
A high-bandwidth data acquisition system for pulse laser radar is developed. Four 250MHz of AD collecting chips are used for data acquisition under clock distribution chip, and then put together for a 1GHz Sps data sample rates. The USB protocol is used for data transmission between system and computer, the AD9520 is used for clock distribution, the FPGA is used for data acquisition, down-conversion, caching and transmission control chip, and the LVPECL and LVDS bus is used to ensure the stability of high-speed data transmission and signal process. The experimental results show that the system can satisfy the data acquisition tasks of the pulse laser radar.
