Abstract
An example method may include transmitting a first acoustic signal from a downhole tool using a transmitter gain in a transmitter circuit. A first echo signal associated with the first acoustic signal may be received at the downhole tool using a receiver gain in a receiver circuit. At least one of the transmitter gain and the receiver gain may be adjusted based, at least in part, on the received first echo signal and at least one previously received echo signal.
Claims20
A method, comprising:
- transmitting a first acoustic signal from a downhole tool using a transmitter gain in a transmitter circuit;
- receiving at the downhole tool a first echo signal associated with the first acoustic signal using a receiver gain in a receiver circuit;
- adjusting the transmitter gain, at least in part, on the received first echo signal and at least one previously received echo signal;
- and
- adjusting the receiver gain based, at least in part, on an optimal level associated with an analog-to-digital convertor of the tool.

A system, comprising
- a downhole tool;
- a transducer coupled to the downhole tool;
- a transmitter circuit coupled to the transducer and characterized by a transmitter gain;
- a receiver circuit coupled to the transducer and characterized by a receiver gain;
- and
- a controller communicably coupled to the transmitter circuit and the receiver circuit and configured to
- cause the transmitter circuit to transmit a first acoustic signal from the transducer using the transmitter gain;
- cause the receiver circuit to receive from the transducer a first echo signal associated with the first acoustic signal using the receiver gain;
- and
- adjust the transmitter gain, at least in part, on the received first echo signal and at least one previously received echo signal;
- and
- adjust the receiver gain based, at least in part, on an optimal level associated with an analog-to-digital convertor of the tool.
