Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
As shown in Fig. 2, the adjustable multibeam sonar of the numbers of beams of the utility model embodiment, comprising: sonar transmitting transducer,
Sonar receives energy converter, track, memory and processor.
Specifically, sonar transmitting transducer is fixed in Sonar system, the fixed position of sonar transmitting transducer emits sound wave.
Since transmitting transducer position is in stationary state on Sonar system, the phase of multiecho acoustical signal thereby may be ensured that
Information rule is consistent.
Sonar receives energy converter and is installed on track-movable on track, and sonar receives energy converter in different location reception sound
The echo-signal of transmitting transducer.
In one embodiment of the utility model, sonar receives multiple positions that energy converter is advanced in orbit, by mesh
