The scanner unit is an antenna that transmits a radar
signal into space, and sends the radar signal reflected
from a target into the equipment. The horizontal antenna
beam width is small for identifying the target bearing, and
the scanner unit has a rotating mechanism for detection in
the entire surrounding area.
Two types of scanner units are provided for this
equipment, and their usage is as follows:
Ԙ X band (10 kW) scanner unit: Compact and light
