MSC Introductory Weather Radar Course

A change in signal power, voltage or current. Usually applied to a change greater than one and expressed in decibels.

Gauge adjustment is a solution to problems connected with range effects, calibration level, and limited extent effects. Gauge adjustment is any procedure that makes partial changes in the characteristics of radar data in order to correspond radar derived measurements to the results given by gauge measurements.

The pattern produced as random intensity fluctuations on an A-scope, usually caused by noise. It appears as closely spaced, sharp, time varying pulses.

Occurs independently of propagation conditions. It can be permanent and severe. Its occurance depends on radar location and on its scan strategy configuration. Minimization of ground clutter effects depends upon intelligent siting and signal processing.
