“…Combined with the actual boundary conditions, the analytical expression of the transient temperature field of the material is derived based on integral transformation. In [29], under the condition that the tracking error of the system is a homogeneous square derivable, each state is experienced in a zero-mean normal process. The authors derived the equation for the dynamic damage probability level of a high-energy laser system by means of clear physical concepts and rigorous mathematical deduction.…”

“…In [30], the authors define the damage probability of a high-energy laser system under the conditions of successful target capture and conduct an analysis. The authors do not combine specific target characteristics to analyse the damage probability in detail in [29,30]; although the authors combine target characteristics, the model granularity is large and the results are not accurate enough in [5,6]. In [23], the authors determine the average spot intensity distribution under the effect of turbulence and tracking and aiming errors, but they do not provide the form of the probability distribution of spot intensity, which is not conducive to the subsequent modelling of the damage probability.…”

The paper proposes a method that analyses the dynamic damage probability of laser systems to address the shortcomings of the quantitative model for the damage probability of laser systems. Firstly, the far-field energy density distribution model is constructed according to the power spectrum inversion method. Then, the instantaneous on-target spot power density distribution is equivalently portrayed based on the combination of the far-field power density and the missile target characteristics. Next, the instantaneous on-target spot is combined with the tracking and aiming error to obtain the probability distribution of the energy density of the long-period on-target spot. Finally, the temperature probability distribution is obtained by analyzing the relation between the target energy density and the temperature of the inner wall of the warhead. Consequently, the damage probability was calculated. The simulation shows that there is a unique maximum damage probability when the target is flying in a straight line and the laser system strikes the missile sideways. The method can provide support for the shooting timing of high-energy laser systems.
