Embodiment Construction

[0012] refer to figure 1 . According to the present invention, the probability of an aircraft entering the opponent's air defense detection system to effectively search the airspace is related to the guidance probability of the opponent's detection equipment, the accuracy of the navigation system, the characteristics of the ground air defense detection equipment, and the terrain / weather conditions of the target area. The ground air defense detection area is the simultaneous detection area X of each detection unit of the air defense detection system i (i=1,...,m) union (X 1 ∪X 2 ∪…∪X m ) form the enveloping area. Judging whether the aircraft has fallen into the effective search airspace of the opponent's detection system is to judge whether the combat aircraft exists in the above-mentioned enveloping airspace at the current moment. The method is to transfer the geographic coordinates of the trajectory of the combat aircraft to the opponent's ground air defense detection sys...

Abstract

The invention discloses a method for establishing a ground attack survivability probability model of an aircraft platform system, and aims to provide a modeling method which is high in practicabilityand capable of clearly expressing aircraft survivability and survival probability of defense penetration success. The method is realized through the following technical scheme: judging whether the airplane falls into an effective search airspace of an opposite side detection system; transferring the geographic coordinates of the trajectory of the aircraft into a detection coordinate system of eachground air defense detection system of the opposite side; solving the relative position of the combat aircraft to the detection device; judging whether the combat aircraft at the current moment fallsinto an effective search airspace of an opposite side detection system or not, wherein the occurrence probability of the event is the probability that the aircraft enters an effective search airspaceof an opposite side detection system; and calculating the survival probability of the combat activity at each moment in each stage in combination with the fault occurrence probability of the aircraftin the task execution process, thereby constructing an aircraft platform system survival capability probability model.

Description

technical field [0001] The invention relates to a method for establishing a probability model of an aircraft platform system's ground attack survivability, and is also applicable to the evaluation of survivability, penetration effectiveness, killing effectiveness and mission completion effectiveness. Background technique [0002] According to the evaluation methods and methods, the evaluation methods of combat aircraft's ground attack combat effectiveness can be divided into five categories: flight performance comparison method, analytical calculation method, air combat simulation method, expert evaluation method, and experimental statistics method. The characteristic of the analytical calculation method is to calculate the index value according to the analytical expression describing the functional relationship between the performance index and the given condition. This analytical expression can be established directly based on the theory of military operation research, or ...
