Research on infrared detection and image simulation of ships applied to underwater unmanned vehicles

Underwater unmanned vehicles are important carriers for conducting ocean exploration activities, and surface vessels are the main detection objects for underwater unmanned vehicles to conduct surface exploration. This article takes surface ships as the research object, based on the basic radiation theory in physical optics, summarizes and analyzes the current research status of surface ship detection, and based on thermodynamic models, studies the modeling and simulation methods of the infrared radiation characteristics of ships themselves; Based on the environmental characteristics of ships in the marine environment, the modeling and simulation methods of infrared radiation reflected by ships in the environment were studied; Based on an atmospheric model, a simulation method for atmospheric transmittance during infrared radiation transmission was studied; Based on the linear quantization method, the modeling and simulation methods for infrared imaging of ship targets were studied, and the infrared simulation images of ships were obtained. The research and simulation results of the theoretical calculation model for the temperature field and infrared radiation characteristics of ship skin in this article have certain reference value in the research of infrared detection and recognition of underwater unmanned vehicles against ship targets.
