Waveform Sampling Airborne lidar with multi-target detection and high-precision three-dimensional mapping capability is the development trend of laser radar technology in the future. Array detection system based on fringe principle Laser imaging radar has broad application prospects in laser surveying and mapping because of its full-waveform echo data sampling capability and high integration. A new type of lidar system based on the fringe principle of full waveform sampling area array detection system was introduced. The noise in the echo signal of the new type of lidar was extracted and the statistical rule of the new type of laser radar echo noise was obtained. Compared with the statistical characteristics of the target total echo signal, a new method of de-noising the echo signal is proposed.
