A slotted waveguide array antenna with gain not greater W ARN ING 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 possible personnel. This is the minimum safe separation distance estimated to meet all RF exposure compliance 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. FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE FCC MAXIMUM 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. 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. Determining MPE Radius THE 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. 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 metallic 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.

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. ■ Side-lobe echoes Radiation 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. Main beam Side lobes True echo False echoes ■ Indirect echoes Indirect 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. Target True echo Scanner False echo Mast or similar obstruction Target Own ship True echo Bridge Indirect echo An echo is reflected at this point. 12 MXR-5000T / Page 13-2-15 BASIC RADAR THEORY ■ Multiple echoes Multiple 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. False echoes Own ship True echo Another ship ■ Minimum range Detection 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. Vertical beam width 10 11 This target can not be recognized with radar. Pulse length Pulse starting point The target in this area can not be recognized. 12 13 14 15 16 17 18 19 20 21 13 MXR-5000T / Page 13-2-16 BASIC RADAR THEORY ■ Blind and Shadow sectors Blind or Shadow sectors may exist because of obstructions such as masts, derricks or stacks. 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. Shadow sector 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. Blind sector Mast or similar obstruction Own ship Large island Small island ■ Target resolution Target 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 D Direction resolution When two targets are separated by more than the pulse width, they appear as two echoes. When two targets are separated by more than the horizontal beam width, they appear as two echoes. When two targets are not separated by more than the pulse width, they appear as 1 echo. When two targets are not separated by more than the horizontal beam width, they appear as one echo.
