This paper deals with the equivalent circuit of the transformer-coupled streamer and its calculation. The differential equation, the expressions of the amplitude and phase response as well as the sensitivity of the pressure geophones have been derived. It has been proved that the theoretical resultants are in accord with the actual data of several kinds of streamers fairly good. The selection of some parameters of the circuit by the method mentioned above has been discussed at the end of this paper.
