● Avoid central locations on tall, narrow vessels
● Nozzle must be vertical and clear of imperfections
Beam width depends on antenna size and is approximate: see below.
For details on avoiding false echoes, see Auto False Echo Suppression.
● Beam angle is the width of the cone where the energy density is half of the peak energy
density.
● The peak energy density is directly in front of and in line with the antenna.
● There is a signal transmitted outside the beam angle, therefore false targets may be
detected.
