The invention provides a ship head sonar platform capable of reducing vibration energy transmission, aims to reduce the influence of vibration energy transmission on self noise of the ship head sonar platform, and belongs to the technical field of ship vibration and noise reduction. The sonar platform comprises a hydraulic spring damping device, a transmission rod buffer device, a positioning block fixing device, a hydrophone array and the like, the transmission rod buffer device comprises a platform, a transmission rod, a supporting spring and the like, the transmission rod comprises two rod bodies hinged to each other, and the upper end of the platform is connected with an upper deck through the hydraulic spring damping device. The positioning block fixing device comprises an upper positioning block and a lower positioning block which are connected in a matched mode, the lower positioning block is connected with the lower deck, the hydrophone array comprises a plurality of hydrophones, an elastic rope and two rigid rods, the two ends of the elastic rope are connected with the two rigid rods respectively, and the hydrophones are arranged on the elastic rope at certain intervals. The sonar platform is mainly used for reducing the background noise of the sonar area at the head of the ship and improving the sonar detection level.
