Study on model of laser interference on UAV detector

Abstract

With the rapid development of UAV technology, the jamming method of UAV has attracted more and more attention from various countries, which makes the jamming model of laser on UAV detector have been studied deeply.By analyzing the working mode of UAV detector, an equivalent experimental system of laser irradiation optical detector was established in the laboratory environment. The corresponding relationship between pixel saturation and power of detector and the irradiation effect of single beam and double beam laser on detector under different angles were analyzed experimentally. The results show that the saturation spot size of the detector has an approximate linear relationship with the laser incident power, and different saturation interference laser power can be obtained according to the different properties of the sensor. Through the analysis of the established physical model that the incoming power of a single laser varies with the detection Angle, it shows that a single laser only has a certain irradiation effect on the detector below the deflection Angle of 50°. Symmetrical dual laser beam can improve the damage effect of optical detector.
