摘要When evaluating the detection probability of a pulsed Gm-APD laser ranging system with a propagation path close to the ground, the detection probability limitation caused by the atmospheric turbulence cannot be ignored. Based on modulated Poisson model, the detection probability limitation due to the turbulence effects is investigated, and a cumulative pulses detection method is proposed to restrain the turbulence effects. The results show that the influence of the turbulence effects is equivalent to adding a new noise source to the echo intensity, the detection probability results in a worse situation with stronger turbulence effects, when the turbulence degree is 1.5 and the echo intensity is 10, the target detection probability decrease by 0.17, and the false alarm probability increases by 0.03. By utilizing the cumulative pulses detection technique, the target detection probability and false alarm probability improve by 0.3 and 0.07, respectively.
