Sea state
The range of variation of the Q0N frequency used for transmission waves of a
solid-state radar. Generally, the greater the frequency deviation range, the
higher the resolution in the range direction.
A procedure of enabling the chart supplied by Base CD to be displayed on
ECDIS
: A device to switch over two or more radar display units and two or more radar
antennas
: Line between two consecutive waypoints
: A target symbol representing the last valid position of an AIS target before the
reception of its data was lost, or its last dead-reckoned position.
: One for which target information is no longer available due to poor, lost or
obscured signals.
: A radio frequency amplifier circuit consisting of semiconductor elements used
for solid-state radars. It employs a high frequency, high power FET.
: Main positioning sensor
: 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.
: A navigation aid which responds to the radar transmission and generates
radio wave
: An area of the chart displayed on the screen. Represented by one half of the
length of the chart display screen.
: A fixed target specified to calculate the speed over the ground
: User report to be issued periodically for using the Dynamic License method of
Jeppesen continuously
: Border that indicates the selected range.
: Radar Interface Circuit(Option interface board in Junction Box)
: The display scale
: Status of the sea condition due to the weather environment, expressed as a
sea state 0 for flat conditions with minimal wind, to sea state 8 for very rough
sea conditions.
