摘要：

In order to solve the problem that the echo dynamic range is far greater than the range of the linear amplifier, this paper presents a short-range dynamic laser echo ranging approach. This method could generate wave by the FPGA and high speed DAC circuit, and then the STC ( sensitivity time control) circuit could weaken the influence of the large echo dynamic range. Theoretical calculation and experimental results show that this scheme can be used for short-range laser radar echo processing, which not only can extend the distance of the dynamic range, but also can improve accuracy ranging. This method would be widely used in short-range laser radar systems.
