The miniaturized, high-energy-output mini-SOSIE has become an important source in seismic exploration. It has seriously impeded resolution because of the coherent vibration frequency and periodical problem of the signal. In order to solve these problems, this paper designed a vibrator signal generator. In this paper, a pseudorandom coding technique is tested as a sweep control method for mini-SOSIE. The pseudorandom coding sequence is produced by Matlab and is of good auctocorrelation characteristic. By comparing experimental field data from sources which is controlled by pseudorandom coding method and the rammer, the pseudorandom scheme yields significant improvements, and greatly improved signal-to-noise (SNR) and resolution.
