of antenna in radar level measurement, horn, parabolic, rod, and waveguide.
Auto False-Echo Suppression
a technique used to adjust the level of a TVT to avoid the reading of false echoes. (See TVT.)
Auto-False Echo Suppression Range
defines the endpoint of the learned TVT distance. This is used in conjunction with auto false
echo suppression.
beam angle
the angle diametrically subtended by the on-half power limits (-3 dB) of the microwave beam.
beam spreading
