To Millimeter-wave Detection Information Processing Research

The paper is one important part of "Millimeter Wave Detecting System of runway recognition" , which is the National Defense advanced research project. The problem of the on bomb MMW passive detecting system signal processing is systematically investigated.To raise the target recognition rates, wavelet analysis .wavelet neural Network and information fusion are introduced. In the paper, as for the very weak signal , the algorithms based on wavelet transform are described in order to improve the signal. The experiment of emulating their ability of discrimination archieves satisfying results.Finally, we have completed the designing and debugging related circuits of signal processing system, include target recognition circuit.The paper analysis the target recognition scheme of on bomb MMW detecting system, which works at passive , and then realize them in some degree , all those can provide powerful guarantee for design the whole MMW detecting system.
