Open Array Radar Scanners offer detailed target separation.
August 17, 2006 -
GMR(TM) 404 and GMR 406 are 4 and 6 ft antennas with 1.8° and 1.1° horizontal beam widths, respectively. Both 4 kW X-band digital open array radar scanners have max range of 72 nautical miles. All radar data is digitally processed within pedestal via DSP, which also features access panel for in-field maintenance. Along with MARPA (Mini Automatic Radar Plotting Aid) capability, products offer radar overlay capability as well as automatic and manual sensitivity and tuning controls.

Garmin® Debuts Open Array Radar
Four- and Six-Foot Antennas Give Boaters the Big Picture
OLATHE, Kan., July 14 -- Garmin International Inc., a unit of Garmin Ltd. (NASDAQ:GRMN), today announced the debut of the GMR(TM) 404 and GMR 406, two powerful 4kW X-band digital open array radar scanners that offer outstanding clarity, precision and target definition.
The GMR 404 is a 4-foot scanner with 1.8-degree beam width for superior target separation. The GMR 406's 6-foot antenna takes beam width down to 1.1- degrees for an even higher level of detail. Both scanners have a maximum range of 72 nautical miles.
"Our new line of open-array scanners solidifies Garmin as a top choice for mariners who own larger motor yachts," said Gary Kelley, Garmin's vice president of marketing. "The GMR 404 and 406 are great additions to our feature-packed and easy-to-use Garmin Marine Network family."
All radar data is digitally processed within the GMR 404 and 406's pedestal via a digital signal processor, and is efficiently presented on Garmin's GPSMAP(R) 3000 series of chartplotter/multifunction displays (MFDs). Digital processing allows for more precise recognition, enhancement, and filtering of radar echoes -- making the finished display easier to read and interpret.
The sleek, windswept styling of the GMR 404 and 406 is also designed to look great atop any modern yacht. The radar pedestal also features a unique access panel for maintenance in the field -- awkward struggles with a heavy and cumbersome radar pedestal are things of the past.
The GMR 404 and 406 both have radar overlay capability, allowing boaters to reconcile radar signatures with known objects on the chartplotter. The units also offer MARPA (Mini Automatic Radar Plotting Aid) capability, which allow boaters to track the bearing, course, speed and predicted closest approach (by both time and distance) of up to 10 targets. MARPA functionality requires an optional heading sensor.
Both radar arrays feature automatic and manual sensitivity and tuning controls, including gain, sea clutter, and rain clutter -- which allows boaters to spend less time tuning the unit and more time navigating. The units also boast selectable interference rejection, which mitigates the effect of nearby radar transmissions.
Other specifications for the GMR 404 and GMR 406 include:
-- Antenna type: End fed slotted waveguide
