THE SIMULATION MODEL ALGORITHM TO ASSESS ACTIONS OF UNMANNED COMBAT AERIAL VEHICLES

Abstract

The increase of combat capabilities of UCAVs brought them to the main range of means to defeat the enemy in both defensive and offensive operations. Therefore, the relevance of issues related to the justification of rational approaches to combat operations planning with the use of unmanned combat aerial vehicles makes it necessary to develop methods to evaluate such operations. This research direction has an important applied value. The article proposes an approach to create a simulation model to evaluate unmanned aerial vehicles actions. The research subject is the planning process of the unmanned combat aerial vehicles use. The work aim is to justify approaches to create ways to evaluate the actions of unmanned combat aerial vehicles based on the simulation model of the researched process. The research uses the discrete-time simulation method. The proposed simulation model essentially simulates two processes: the UAV flight process and the process of the enemy targets detecting. As a rule, the aircrafts flight in space is described by differential equations of motion. This approach requires the implementation of a continuous flow of model time, which leads to significant computational difficulties when building the model. Taking into account the necessary accuracy in the simulation model being created, it is permissible to proceed to a discrete change of the model time with some step comparable to the analyzed processes. This model links together such parameters as the barrage zone scope, the target detection intensity, the number of unmanned combat aerial vehicles, their weapons, and speed. When these parameters are varied, it becomes possible to establish the necessary dependencies between them. This can serve as the basis to develop rational ways of using unmanned combat aerial vehicles under the given conditions. The proposed simulation model can be used in the decision-making support system for combat planning with the use of unmanned combat aerial vehicles.
