A  slotted  wave-guide array antenna with gain not greater than 27 dBi must be mounted a minimum of 5.5 meters (measured from the lowest point of the antenna) vertically above the main deck and all possi-ble  personnel.  This  is  the  minimum  safe  separation distance  estimated  to  meet  all  RF  exposure  compli-ance requirements. This 5.5 meter distance is based on  the  FCC  Safe  Maximum  Permissible  Exposure (MPE) distance of 3.5 meters added to the height of an adult (2 meters) and is appropriate for all vessels.For watercraft without suitable structures, the antenna must  be  mounted  so  as  to  maintain  a  minimum  of 1  meter  vertically  between  the  antenna,  (measured from the lowest point of the antenna), to the heads of all persons AND all persons must stay outside of the 3.5 meter MPE radius.Do not transmit with radar and antenna when persons are  within  the  MPE  radius  of  the  antenna,  unless such  persons  (such  as  driver  or  radar  operator)  are shielded  from  antenna  field  by  a  grounded  metal-lic barrier. The MPE Radius is the minimum distance from the antenna axis that person should maintain in order to avoid RF exposure higher than the allowable MPE level set by FCC.FAILURE  TO  OBSERVE  THESE  LIMITS  MAY ALLOW  THOSE  WITHIN  THE  MPE  RADIUS  TO EXPERIENCE  RF  RADIATION  ABSORPTION W H I C H   E X C E E D S   T H E   F C C   M A X I M U M PERMISSIBLE EXPOSURE (MPE) LIMIT.IT  IS  THE  RESPONSIBILITY  OF  THE  RADAR OPERATOR  TO  ENSURE  THAT  THE  MAXIMUM PERMISSIBLE  EXPOSURE  LIMITS  ARE OBSERVED  AT  ALL  TIMES  DURING  RADAR TRANSMISSION.  THE  RADAR  OPERATOR  IS  TO ENSURE  THAT  NO  BYSTANDERS  COME  WITHIN THE  RADIUS  OF  THE  MAXIMUM  PERMISSIBLE EXPOSURE LIMITS.Determining MPE RadiusTHE  MAXIMUM  PERMISSIBLE  EXPOSURE  (MPE) RADIUS HAS BEEN ESTIMATED TO BE A RADIUS OF ABOUT 3.5 M PER OET BULLETIN 65 OF THE FCC.THIS  ESTIMATE  IS  MADE  ASSUMING  THE MAXIMUM  POWER  OF  THE  RADAR  AND ANTENNAS  WITH  A  MAXIMUM  GAIN  OF  27  dBi ARE USED FOR A SHIP MOUNTED SYSTEM.MXR-5000T / Page 13-1-4

512BASIC RADAR THEORY■IndirectechoesIndirect echoes may be returned from either a passing ship, or returned from a reflecting surface, such as a mast on your own ship.An indirect echo from a reflecting surface will appear on a different bearing from the direct (true) echo, but the distance will be approximately the same for both.■Side-lobeechoesRadiation can escape on each side of the beam inside the lobes. If a target reflects this radiation, it will be displayed on the screen as an echo. Side-lobe echoes usually occur at short ranges and as a result of large (strongly reflective) targets. They canbereducedwithproperadjustmentofthe[SEA]control. Radarusesaformofelectromagneticradiation,whichlikelight,canbereected.Becauseofthisproperty,someobjects may cause false echoes on the screen where in fact no targets actually exist. These echoes may appear if a large vessel, bridge, or tank is in proximity. Operators should be familiar with the effects of these phenomena. In some cases, echoes can be reduced.

135BASICRADARTHEORY■MultipleechoesMultiple echoes may appear when a short-range and strong echo is received from a ship, bridge, or breakwater. Multiple echoes will appear beyond the target’s true echo point on the same bearing of a large target. They can be reduced with proper adjustment of the [SEA]control.■MinimumrangeDetection at short range is very important. Minimum range is determined primarily by transmitter pulse length, vertical beam width and height of the scanner unit. The shorter the transmission time, the quicker the return echoes can be received and their distance measured. The ability to see targets very close to the ship is decreased if the scanner is mounted too high off the water, because the bottom of the vertical beam of the scanner cuts off nearby targets.This target can not be recognized with radar.The target in this area can not be recognized.Pulse lengthPulse starting pointVertical beam widthOwn ship Another shipTr ue echoFalse echoes123456789101112131415161718192021MXR-5000T / Page 13-2-15

An obstruction may throw either a complete or partial shadow as shown in the diagram below. If a target is in a shadow sector, target echoes may not appear on the screen.When tall and massive targets such as a large island are located at close range also shadowed without producing any echoes. This phenomenon is called blind sector. It is very important to know the bearings and widths of all shadow sectors caused by your own ship’s obstructions.■TargetresolutionTarget resolution is determined by the horizontal beam width and transmit pulse width. Sometimes it is difficult to detect two targets which are separated by short distances or which are in the same direction.DDistanceresolution  When two targets are separated by more than the pulse width, they appear as two echoes.    When two targets are not separated by more than the pulse width, they appear as 1 echo.
