Pulse compression : Correlation processing performed when a transmitted chirp signal is
received by a solid-state radar after reflecting off the target. This
processing gain enables the radar to have necessary detection
capability even when a transmission power is low.
Radar beacon : A navigation aid which responds to the radar transmission and
generates radio wave
Range : An area of the chart displayed on the screen. Represented by one half
of the length of the chart display screen.
Range side lobe : False image that is generated as a result of pulse compression
processing in the solid-state radar when there is a large target such as
a large ship in the vicinity.
Reference target : A fixed target specified to calculate the speed over the ground
Rubber band : Border that indicates the selected range.
Scale : The display scale
Sea state : The average height of the wave expressed by dividing into several
classes.
Sleeping AIS target : A target indicating the presence and orientation of a vessel equipped
with AIS
Spot depth : Numeric representation of depth
SSR: Solid State Radar : Radar that uses semiconductor elements instead of magnetron, which
requires periodic replacement. It is built with a system that ensures
necessary detection capability even when a transmission output is low,
by using chirp signals with a long pulse length upon transmission and
performing pulse compression upon reception
