| footprint |
The area of seabed affected by the increase in the level of sound from an outgoing sonar pulse during, or after, a specific period of time. A smaller footprint of sonar on the seabed will result in a higher resolution image in the data. The footprint in the range dimension decreases in size as the sonar pulse propagates away from the transducer. The footprint in the transverse dimension is a function of horizontal beam angle and beam spreading.

| footprint |
This is a measure of the area of sensitivity under the aircraft of an airborne geophysical system. The footprint of an electromagnetic system is dependent on the altitude of the system, the orientation of the transmitter and receiver and the separation between the receiver and transmitter, and the conductivity of the ground. The footprint of a gamma-ray spectrometer depends mostly on the altitude. For all geophysical systems, the footprint also depends on the strength of the contrasting anomaly.
