Abstract:

The article describes the performances of the wave-carrier transmitter for seismic exploration which is designed and manufactured by us.The wave-carrier transmitter has following technical characteristics:(1) Linear level range in channels>90 decibels.(2) The number of channels is 30.(3) The interference between channels<10^-3.(4) It has high resistance to the interference of industrial electricity and the interference of other atmospherics.The article relates the technical approaches of realizing above mentioned aims and provides correlation records of lab analog experi-ment and field experiments.
