Abstract
For marine seismic data acquisition needs,a multichannel marine seismic data acquisition unit was designed,which used the 32-bit analog-to-digital ADS1282 as a core and Field programmable gate array (FPGA) as the acquisition controller.The unit can achieve multichannel seismic data sampling and transmission functions.The design fully used with the design ADS1282 chip integration,with the corresponding anti-jamming measures,not only simplified the circuit design,but also ensured the quality of signal acquisition and system stability.the design used FPGA to realize a multichannel hydrophone signal synchronization sampling.
