Abstract
A system and method simultaneously transmits sound waves through a plurality of sonar elements without interference, such as for the purpose of tracking objects underwater. The system has a pulse generator with a plurality of transceivers connected to the pulse generator. A plurality of sonar elements is connected to the plurality of transceivers, with at least one sonar element per transceiver. A sonar signal is sent from the pulse generator to each sonar element, passing intermediately through a transceiver.
Claims21
A system for simultaneously transmitting a sonar signal, comprising:
- a pulse generator;
- a plurality of transceivers connected to the pulse generator;
- and
- a plurality of sonar elements, with each sonar element connected to one of the transceivers, so that each sonar element emits the sonar signal in synchrony upon receiving a pulse from the pulse generator.
A method for reducing interference between a plurality of sonar elements, the method comprising the steps of:
- providing a system comprising a pulse generator, a plurality of transceivers connected to the pulse generator, and the plurality of sonar elements each of which is connected to the pulse generator through one of the transceivers;
- transmitting a signal from the pulse generator so that the signal reaches each of the sonar elements in a synchronized manner;
- emitting a sonar pulse based upon the signal from each of the sonar elements in a synchronized manner;
- and
- receiving at each sonar element a reflection of signal emitted by the sonar element.
