摘要： The present invention discloses a near-sea-bottom hydrate detection system, which includes a ship-borne part and a deep-towing part. The ship-borne part includes: a comprehensive monitoring host, configured to send an acquisition triggering pulse signal, and transmit the signal to the deep-towing part; and receive near-sea-bottom information acquired by the deep-towing part, and determine a near-sea-bottom condition according to the near-sea-bottom information. The deep-towing part includes: a data acquisition unit, configured to acquire near-sea-bottom information at a current position according to the acquisition triggering pulse signal; an electric spark vibration source, configured to generate an electric spark vibration signal according to the acquisition triggering pulse signal; and a multi-channel data-acquisition electronic cabin, connected to the comprehensive monitoring host, the data acquisition unit, and the electric spark vibration source separately, and configured to transmit the acquisition triggering pulse signal to the electric spark vibration source and the data acquisition unit, and transmit the near-sea-bottom information acquired by the data acquisition unit to the comprehensive monitoring host. In this way, the Fresnel radius can be reduced, and the detection resolution can be improved.
