Transmission signal shaping systems and methods

A method comprising:

• receiving a digital shaping control signal provided by a logic device;
• and
• controlling a transmitter to provide a shaped transmission signal to a transducer, wherein the transducer comprises a single channel or multichannel sonar or radar transducer, and wherein the controlling the transmitter comprises:
• generating a shaped voltage based, at least in part, on the digital shaping control signal, and
• generating the shaped transmission signal based, at least in part, on the shaped voltage and a transmission control signal provided by the logic device.

A method comprising:
