Dsp-based Infrared Multi-detector Information Processing Technology

In this paper, we focused on the application research of the multiple element detector, which is used some type of infrared guidance missile. In view of the Digital Signal Processor, the theoretical study, the scheme for application and the simulation research of this infrared guidance system is studied in detail.The main contributions are showing as follows:1 Based on the theory and specialty of four-element and infrared guidance system, a new method of calculating the relative location of the target and forming the instruction for the infrared missile to tracing the target is proposed in this thesis.2 By analyzing the requirements of hardware and software , a new way of designing the infrared missile control computer is brought out, grounded on the TMS320C2000 in stead of ordinary single chip microcomputer .3 The design principle and scheme, the choice of hardware, the program of software and the connection of module are given in detail.4 Some methods of improve the infrared guidance missile's probability of against infrared decoy using the four element detection system are proposed, after analyzing the specialty of some kinds of infrared jamming .5 Finally, the demonstration and simulation of the multiple element detector system are realized on the basis of Visual C++. The result shows that the design of hardware and software can realize the demands of the infrared guidance missile system by high precision and high speed simultaneously.
