Abstract：In view of the characteristics of wide signal frequency range,large number of acquisition channels and complex noise composition of the tested product in the process of testing the electrical parameters of a certain type of artillery-launched mis-sile component,high requirements are put forward for the sampling rate,number of acquisition channels and signal processing algo-rithm of the acquisition system.At present,most of the signal acquisition equipment in the missile production line is still at the tech-nical level of single station,low sampling channel number,and signal processing algorithms are mostly more traditional low-pass,high-pass and band-pass filtering algorithms,which cannot effectively process noise signals with complex components.Based on the comprehensive evaluation of integration,reliability and denoising,an FPGA multiplexing system based on ICEEMDAN signal decomposition is proposed,which solves the limitations of the current system when acquiring multiple,wide frequency range and complex signals with noise components.Through experiments,the functional realization of 32 parallel acquisition,test accuracy and signal active component extraction of the system are fully verified.
