Abstract

Laser anti-drone technology is entering the sequence of actual combat, and it is necessary to consider the vulnerability of typical functional parts of UAVs. Since the concept of ''vulnerability'' was proposed, a variety of analysis programs for battlefield targets to traditional weapons have been developed, but a comprehensive assessment methodology for targets’ vulnerability to laser is still missing. Based on the shotline method, this paper proposes a method that equates laser beam to shotline array, an efficient vulnerability analysis program of target to laser is established by this method, and the program includes the circuit board and the wire into the vulnerability analysis category, which improves the precision of the vulnerability analysis. Taking the UAV engine part as the target of vulnerability analysis, combine with the ''life-death unit method'' to calculate the laser penetration rate of various materials of the UAV, and the influence of laser weapon system parameters and striking orientation on the killing probability is quantified after introducing the penetration rate into the vulnerability analysis program. The quantitative analysis method proposed in this paper has certain general expansibility, which can provide a fresh idea for the vulnerability analysis of other targets to laser.
