Creation,Simulation And Transmittal Of Infrared Radiation Image

Infrared emission is the property of all objects. Infrared ray bears merits that precede common electromagnetic wave's and light's. Infrared imaging can carry through in the night. So Infrared imaging technology is introduced into many respects(e.g. space spy, missile guidence, medical diagnosis). In respect of missile guidence, infrared imaging guidence is one of the most important precision guidence technologies. It captures the whole infrared emission as its guidence infomiation. It has much more information and more powerful antidisturbance capability than traditional infrared guidence. Many countries are in competion of studing infrared image guidence techology, which include our country. So It is imaportant and significant to simulate infrared emission of the aeroplane. Data transmision and Digital communication are parts for space spy satulates and space stations.,which also capture infrared images of tagets. The infrared iamge data need to be sent back to the ground. Therefore, this article take simulation of infrared mission of aeroplane and image data transformation as main task. The main content of this article includes 1. The mechanism and law of infrared emission of aeroplane,the property of infrared disturbance bomb, the law of the attenuation effect to the transformation of infrared emission produced by the atmosphere are stiudied. The infrared radiation consists fo six parts, i.e. aeroplane hot part emission, aeroplane plume emission, skin thermal emission, reflected skyshine, reflected earthshine, reflected solar radiation. The 3 primary parts, the front 3 parts of them are analyzed particularly. 2. Aeroplane geometry is carved up into small parts according to the tempture difference4 emission of every part is calculated; the transmissity of atmosphere is calculated; the ultimate result of emission obtained by the infrared detector. 3. Based on the 2nd step's results, 3-D graph of aeroplae are produced with OpeGL, which is covered with different colors to show diferent emission. The infrared image is dynamic because of aeroplane graph's motion. 4. The infrared emission image data are captured and sent through the local LAN in accordance with the data system of Anvanced Orbiting System(AOS). AOS is formulated by the Consultative Committee forSpace Data Systems (CCSDS) for complex aircrafts?data commucation. Every service and its data unit format and the structure of Space Link Subnet are analyzed. Bitsteam Service and Virtual Channel Data Unit are adopted ror image data transfermation. Befor transfermation,data are compress by JPEG standard and encapsulated by CCSDS format. The netprogram interface is wonsock.
