Abstract

A method for accurately controlling an infrared target interference model comprises the steps: establishing an infrared guidance semi-physical simulation device, wherein a simulation console, a simulation computer and an infrared target simulation system in the infrared guidance semi-physical simulation device are connected with one another to form a simulation closed loop, and a simulation turntable is connected with the simulation computer; after the infrared guidance semi-physical simulation device is powered on and initial setting is completed, enabling the simulation computer to completea dynamics and kinematics model in real time and drives the position and rate of the simulation turntable; meanwhile, enabling an infrared scene simulator in the infrared target simulation system to receive interference control parameters sent by the simulation computer in real time, and setting each module of an infrared interference model generated by the infrared scene simulator according to two control mechanisms of simulation time and missile-target distance of the simulation computer; therefore, the clutter and divergence model of the infrared radiation energy is generated, the infraredinterference model is accurately controlled in real time, and the confidence degree of infrared missile anti-interference performance evaluation is effectively improved.

technical field [0001] The invention relates to the technical field of infrared guidance semi-physical simulation control, in particular to a method for precisely controlling an infrared target interference model. Background technique [0002] The semi-physical simulation system of infrared guidance is divided into three parts: computer control system, flight turntable and infrared target simulation system. Among them, the scale, cost and development cycle of the infrared target simulation system rank first among the three. The simulation of infrared target and jamming motion information, while the target and jamming simulator is a key part of the whole simulation system, the quality of the simulated target and jamming simulator directly affects the fidelity of the simulation system and the evaluation of missile anti-jamming performance.

Problems solved by technology

[0003] In the previous hardware-in-the-loop simulation for the simulation of the background environment and interference of infrared targets, the control machine of the infrared scene generation system was usually manually operated, and the background and interference were synthesized in the infrared scene generation system. The time cannot be accurately grasped, so that the accuracy and real-time performance of the infrared interference model cannot be guaranteed
