The Design and Implementation of A Hardware-in-the-loop Simulation Virtual Environment for Multi-aircraft Tracking and Shooting Control System

In view of the simulation verification requirements of the control system of multi-aircraft tracking and shooting, in the hard-in-the-loop simulation test of the aircraft control system, the original image measurement device and target simulator have high cost and complex debugging degree in the target recognition process, so a physical equivalent device of image measurement based on the relative position of the head and body is designed and realized, solved the test preparation, long cycle, high test cost. The image measurement physical equivalent device based on the relative position of the head and body is referred to as the image measurement physical equivalent device. In addition, in order to meet the requirement that a sub-stage tracking test should be run at the same time with the full aircraft simulation test, a multi-core and multi-threaded parallel real-time simulation platform for multiple flight bodies is used for the first time in the test. The tests show that the closed-circuit guidance simulation test technology of the physical equivalent of the image measurement device approximates the actual application environment, improves the authenticity and reliability of the test, and reduces the test cost.
