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

To address the significant challenges associated with achieving precise target tracking and engagement of high-energy laser systems operating under complex atmospheric conditions, this study proposes an indirect detection strategy based on the characteristics of the laser spot. The core principle of this method involves analyzing the two-dimensional scattered-spot distribution formed after the laser beam interacts with the target surface, encompassing morphological variations and energy concentration patterns to indirectly characterize of target surface features. Furthermore, a multidimensional coupled model was developed, integrating atmospheric transmission effects, tracking-strike errors, and strike efficiency. This model is designed to systematically enhance the laser system’s tracking accuracy and strike effectiveness evaluation by incorporating the attenuation and distortion of laser propagation through atmospheric turbulence and aerosols, along with tracking and pointing error algorithms. The research quantifies the influence of atmospheric factors (such as visibility and turbulence intensity) on laser propagation and further elucidates how these parameters impact tracking and strike effectiveness, thereby offering new technical insights for target perception and performance evaluation of laser systems operating under complex environmental conditions.
