Indirect Detection of Target Tracking and Strike Capability in High-Energy Laser Systems

To address the critical challenges in achieving precise target tracking and engagement with high-energy laser systems under complex atmospheric conditions, this paper begins by introducing an indirect detection strategy leveraging laser spot characteristics. The essence of this approach lies in analyzing the two-dimensional scattered spot distribution generated after the laser beam interacts with the target surface, including morphological variations and energy concentration patterns, thereby enabling indirect characterization of target surface features. Furthermore, a multidimensional coupled model is established that integrates atmospheric transmission effects, tracking-strike errors, and strike efficiency. This model aims to systematically enhance the laser system's tracking accuracy and strike effectiveness assessment by integrating the attenuation and distortion effects of laser propagation through atmospheric turbulence and aerosols, as well as tracking and pointing error algorithms. The research results not only quantify the impact of atmospheric environmental factors (such as visibility and turbulence intensity) on laser propagation but also indirectly reveal how these factors affect tracking and strike effectiveness, providing new technical support for target perception and assessment of laser system effectiveness in complex environments.
