| This paper is mainly about studing the signal processing of MMW/IR compound detection and the system circuit design. Firstly, in this paper a new passive infrared and millimeter wave compound detection system has been adopted and proved. Secondly, the paper also presents the working principle of the IR channel and the MMW channel. Thirdly,the MMW channel modeling and simulation have been detailed in the third part,which includes signals analysis of IR channel and MMW channel. Forthly, according to the detection rate, the wigner method, the principal component analysis, lateral inhibition network, edge-finding method, region growing method and neural network have been used., by which the system detection rate increased. Finally,the signal processing circuit is decided which is based on the system demand.The paper presented a significant study in IR and MMW compound detection system, which is for carrying out the detection system. |
