| Abstract: | This paper introduces a method for analyzing the performance of laser radar based on Geiger-mode avalanche photodiode(APD)array.The detection probability,false-alarm probability and miss alarm probability are researched by analyzing the creation of primary photon electronics and dark count rate noise.Further more,the method of threshold detection with multiple-pulses are proposed,of which the detection probability and false probability are researched and simulated.For a target at a distance of 2 km to 10 km... |
