Infrared / Millimeter Wave Composite Signal Processing Method And Circuit Design

Multimode complex is currently the main direction of development of smart munitions detection, aiming at IR/MMW detection in complex signal processing method and circuits.On the basis of the IR/MMW sensor detection principle, Missile and Target Engagement Process analysis,establish the infrared detection model and IR/MMW wave signal characteristics analysis model; especially demand for infrared sensor test development process,make a in-depth research to several typical metal infrared radiation characteristics, and make use of existing test sensors designed to test and improve the infrared sensor equivalent test methods.On the basis of comparison threshold pulse detection target recognition and neural network recognition algorithm.Thought of currently used of actual project application conditions and requirements, come up with an improved nearest neighbor clustering algorithm training RBF neural network target recognition, by optimizing the network structure, reducing the learning time and improve the recognition probability.Completed the IR/MMW sensor infrared optics, signal detection circuit, data acquisition and storage circuit, target identification circuit hardware circuit design and debugging. With the project acceptance, completed extensive testing of indoor and outdoor experiments, through in-depth analysis of the test data, completed the infrared detection model experimental validation and error analysis, and the use of the experimental towers test data to identify verification and analysis of two target recognition program.
