DMT’s Dorado Radar and Vumii Claritii Camera

The Dorado is a marine radar.  It can act as a navigational aide or as a security radar.   This radar comes in four versions:

  • Dorado Lite (picture at bottom of page)
  • Dorado LP18
  • Dorado LP24
  • Dorado LP24B

Range increases from short range to long range on the list above.    The Dorado Lite is will detect a walking human to about 500 meters.  It will detect a medium size power boat up to 3.5 km.   The Dorado LP24B will detect a human up to about 3 km and medium size power boats up to 10 km.

The Dorado radar is not your ordinary marine radar.   This solid-state system uses very low power (< 1 watt) FMCW technology for high resolution for unmatched clarity.   The Dorado is DMT’s fastest spinning radar with up to 50 RPM rotation rates.   So if fast updates of wide open areas and detection of small objects are important, this radar is the solution.  The Dorado’s fast rotation rate would pick up threats (jet skis, speed boats) quickly and report its position and speed to the map display.  The radome (rigid cover) for this radar has a mounting hole pattern on top for equipment (such as cameras) to be mounted on top.  DMT has made this radar to be maintenance free for more than 2 years.  This radar is exportable.
