(1) Installation Place of Radar
The display unit, scanner unit and inter-unit connection cable should be located apart from the
main unit, feeder, antenna coupler and antenna of radio equipment as far as possible.
Especially, proper installation of the feeder, antenna coupler and antenna of radio equipment is
very important to improve EMI trouble.
(2) Laying Power Supply Cables
Following connections A and B are recommended to reduce conduction noise generated from ra-
dar. Connection C should not be used.
Connection A
(Very Good)
Connection B
(Good)
Connection C
(Bad)
(3) Grounding
All equipment should be firmly grounded at the earth nearest hull with copper plates or braided
wires.
Improvement Procedure for EMI
(1) Confirm grounding on the radar and radio equipment. However, some equipment, on which
grounding is not always necessary, have a possibility of EMI improving when taking off their
grounding. Try to take off grounding.
(2) Confirm power supply cable connections and modify to the connection A or B above.
(3) Try to shift the display unit and inter-unit connection cable of radar to be apart from radio
equipment.
(4) Try to shift the feeder of radio equipment to be apart from each units and the inter-unit connec-
tion cable of radar.
(5) Try to shift the antenna coupler and antenna of radio equipment to be apart from the scanner
unit and inter-unit connection cable of radar.
