Abstract

The invention relates to a tracking type lifting sonar and a sonar control method. The sonar comprises a wet end and an array plane arranged around the periphery of the wet end. The number of the array surfaces is a plurality and is an even number; each array surface comprises at least one transducer array and a hydrophone array, each array surface is connected with the wet end through a connecting rod, the two ends of the connecting rod are respectively provided with a swing device, and the swing devices can drive the connecting rod or the array surfaces to rotate. According to the sonar, thetransducer array and the hydrophone array are both arranged on the array surfaces, each array surface can rotate, and when the position (or angle) of the tracking target changes, the array surfaces can also rotate to a more appropriate position, so that relevant data information of the tracking target can be collected conveniently, and the tracking result is more accurate.

Description

technical field [0001] The present application relates to the technical field of tracking pendant sonar, in particular to a tracking pendant sonar and a sonar control method. Background technique [0002] Sonar is a common device used for underwater detection (such as ocean detection) and target tracking. The current sonar is usually composed of a plurality of array planes, and a receiving array is arranged on the array planes for receiving echo signals. When the sonar is in working condition, the array surface is unfolded by gravity, and its angle is fixed. When the position (such as the orientation) of the tracking target changes, the array surface cannot change accordingly, which may easily lead to inaccurate tracking results. Contents of the invention [0003] Based on this, it is necessary to provide a tracking type hanging sonar and a tracking type for the current sonar that when the position (such as azimuth) of the tracking target changes, the array surface canno...
