| Abstract: | Statistical properties of pulse laser signal detection using SiAPD as a detector has been theoretically studied, and the relation between the preset threshold and detection performance has been analyzed. Theoretical studies indicate that the threshold applied to the discriminator has the decisive influence on the detection performance. Analysis shows that primary photoelectrons and average gain of SiAPD determine the threshold scope within which it can guarantee the laser ranging systems detection probability and false alarm probability. |
