Transceiver for SONAR System

A SONAR transceiver, comprising:

• a digital signal processor (DSP) configured to perform signal processing on the digital transmit signals and digital receive signals;
• a transducer configured to transmit SONAR signals when in a transmit mode and to receive echoes of the transmitted SONAR signals when in a receive mode;
• transmitter circuitry including digital-to-analogue conversion circuitry and operably coupled between the DSP and the transducer, so as to receive digital transmit signals processed by the DSP and to convert those digital transmit signals to analogue transmit signals, the analogue transmit signals provided to the transducer;
• and
• receiver circuitry including analogue-to-digital conversion circuitry and operably coupled between the DSP and the transducer, so as to receive analogue receive signals from the transducer and to convert those analogue receive signals to digital receive signals, the digital receive signals provided to the DSP.
