Embodiment 1

[0133] This example is applied to the calculation of dynamic damage probability of continuous wave intense laser weapon system:

[0134] Let T s =4,T h =2.5,α 0 =0.6, when λ∈[0.1,4], use the formula (1) to calculate the dynamic damage probability as Figure 4 Shown:

[0135] This example shows that the dynamic damage probability is a function of the natural frequency λ with two maxima. Among them, λ=0 corresponds to the tracking error as a strong correlation error. Although λ can be set near zero, when Z(t) is outside the shooting gate, it is difficult to enter the shooting gate as soon as possible to shoot, and another non-zero However, the maximum value can avoid the above defects.

Embodiment 2

[0137] This example is applied to the demonstration and design of the dynamic damage probability of continuous wave intense laser weapon system.

[0138] Let the radius of the circular shooting gate ρ=1, T s =4,T h = 2.5; is the shaping filter after whitening of the tracking error, is the error transfer function of the tracking system; the uncorrelated ergodic function x(t), y(t) output by it is used as the analog quantity of the tracking error in two directions, when T 1 =0.1, select T 2 =0.6, calculated using formula (23):

[0139] σ x = σ y = 1.001;

[0140] Then use formulas (20) and (22) to calculate

[0141] λ=1.209,α 0 =0.394

[0142] Finally, formula (1) is used to calculate the dynamic damage probability:

[0143] H=0.516

[0144] if T 1 =0.1 takes a fixed value, and T 2 ∈[0.1,6] interval changes, as Figure 5 The damage probability curve shown. It is easy to find from the figure that when T 2 = 0.6, λ = 1.209, the damage probability obtains the m...

Abstract

The invention discloses a high-energy laser weapon dynamic damage probability determination method. According to the method, a random passage theory is adopted, and in the normal process that the tracking error of a high-energy laser weapon is an ergodic and zero-mean value which is differentiable in mean square, a dynamic damage probability level expression formula of the high-energy laser weapon is derived; the property of a dynamic damage probability is showed, two optimized random passage natural frequencies exist, and when working in an nonzero frequency mode, a tracking system is able to respond quickly; the quantitative relation between a transfer function of the tracking error and the dynamic damage probability is given. The high-energy laser weapon dynamic damage probability determination method is able to provide an effective calculation method for demonstrating, designing and testing the dynamic damage probability of the high-energy laser weapon and for optimizing the dynamic damage probability according to parameters of the target tracking system of the high-energy laser weapon.

Description

technical field [0001] The invention belongs to the field of weapon system effectiveness analysis, in particular to a method for determining the dynamic damage probability of a continuous wave intense laser weapon. Background technique [0002] As a precise and efficient fixed-point killing weapon, the continuous wave intense laser weapon has become the frontier of the development of tactical weapon systems and has received great attention. When the continuous wave intense laser weapon loaded on the carrier shoots at the moving target, under the same damage definition, only its damage probability is better than that of other types of weapons that have similar missions before it can become an installed weapon. possible. If the damage probability of the strong laser carrier and its shooting target is in relative motion, it is called the dynamic damage probability of the strong laser weapon system. Obviously, establishing a mathematical model of this dynamic damage probabilit...
