Unmanned vehicle, system and method for transmitting signals

A system for transmitting and receiving signals, the system comprising:

• a plurality of transmitting unmanned vehicles spaced from each other, each of the plurality of transmitting unmanned vehicles including a transmitting element that is configured to transmit a signal towards an object, the transmitting elements of the plurality of transmitting unmanned vehicles together forming a phased-array transmitter that emits a transmission beam in a predetermined direction;
• and
• at least one receiving unmanned vehicle including:
• a receiving element that is configured to receive a reflected signal from the object;
• and
• a control unit that is in communication with the plurality of transmitting unmanned vehicles, wherein the control unit is configured to position the at least one receiving unmanned vehicle relative to the plurality of transmitting unmanned vehicles such that the receiving element is spatially clear of a path of the transmission beam.

A method of controlling a plurality of unmanned vehicles, each of the plurality of unmanned vehicles including a transmitting element that is configured to transmit a signal, the method comprising:

• receiving a control signal indicative of a predetermined direction;
• determining positions of the plurality of unmanned vehicles relative to each other;
• regulating the transmitting elements of the plurality of unmanned vehicles to together form a phased-array transmitter based on at least the positions of the plurality of unmanned vehicles;
• and
• emitting a transmission beam in the predetermined direction using the phased-array transmitter.
