Visual Simulation Of Radar/Infrared System And Target Information Acquisition

In the 21 st century,air superiority has been the winning factor of the war situation.Under the complex electromagnetic environment and the development of fourth generation stealth performance,it puts forward higher requirements on the performance of airborne multi-sensor system.Based on radar ranging advantage and infrared goniometer advantage,they usually adopt cooperative engagement mode.The outfield test of airborne multi-sensor system is expensive.So it usually uses computer simulation in the system design and validation process.Project is based on the background of air borne multi-sensor system operations and the development of information fusion.Research direction is the radar and infrared system simulation and target's information acquisition.Firstly, infrared system simulation is based on the Vega visual simulation software. Infrared image has been processed by Open CV.Morphological filtering Tophat suppress the noise and background interference and the mixed gauss background modeling complete target's detection.Then kalman filter predict targets and meanshift algorithm achieve target's tracking.It improved the robustness of tracking. Through the rotation of infrared detector can achieve the target's angles. The modeling of radar system is based on Matlab/Simulink. Simulation of radar system use the same path of infrared simulation.It ensure the trajectory consistency. Pulse compression can improve range resolution and signal to noise ratio.Moving target indication(MTD) can filter out clutter, noise and interference. CFAR detection is to ensure the false alarm rate of target detection. The way of solution fuzzy is to gain the distance and velocity of target. The amplitude and differential method can measure target's angle.Finally,the software of radar and infrared system is designed and completed based on the information processing.The Vega infrared scenein is render in MFC system software by the API class library.Matlab engine technology communicate data between radar system and MFC system.Based on the implementation of radar and infrared system and setting parameters,system can obtain the target's information.It verifies algorithm's correctness and system's stability.
