AN HLA BASED MAN IN LOOP SIMULATION FRAMEWORK FOR AN AIR DEFENCE SYSTEM

Abstract

HLA is software architecture for creating computer models or simulation out of component models or simulations. At the core of the HLA is the software called ‘Run Time Infrastructure or RTI that is responsible for distribution and management of information. HLA has been used for the development of military simulation. In this work, we present a framework for an HLA based man-in-loop simulation. The main focus has been to simulate the real time command and control interface with the operator (man) interacting with the simulation through virtual console. Also the interfaces with sensors and weapons utilize the same interface and mechanism as used by actual sensors and weapons. This framework can be used for evaluation/training of the operator and testing of new weapons. War games are widely used by the military to train troops and develop new ways of war fighting. There are various tools and softwares available that allow the user to create a synthetic/virtual battle field and test various scenarios. These includes OneSAF Testbed Baseline (OTB), STRIVE, MANA. OTB can interact with other live, virtual and constructive simulations based on HLA. In our work we present the ‘Air defense Simulation’ in which some components of the system are simulated/virtual whereas other components are live. In our simulation various simulated targets are generated by the operator and engaged either by the simulated or real gun. Sensors and weapons communicate with each other using standard messages. The simulation is tested in various scenarios for real time performance and detail analysis of results is presented.
