Laser radar total wave signal analyzing method

The invention provides a laser radar total wave signal analyzing method. According to the method, when updating is carried out every time, one of the parameters including the number k of echo signals, noise signals B incident to a laser radar detector, the peak position t0 of each echo signal and the peak amplitude beta of each echo signal is selected at random so that updating can continue to be carried out; the parameter k is updated based on the Metropolis algorithm thought, the parameter B is updated based on the Metropolis algorithm or the simulation tempering algorithm thought, and the parameter t0 and the parameter beta are respectively updated based on the simulation tempering algorithm thought. According to the laser radar total wave signal analyzing method, total wave signals of targets with unknown characters can be processed quickly without being affected by the signal noise ratio of the total wave signals.
