■ Indirect echoes Indirect echoes may be returned from either a passingship, or returned from a reflecting surface, such as amast on your own ship. An indirect echo from a reflecting surface will appearon a different bearing from the direct (true) echo, butthe distance will be approximately the same...

8 BASIC RADAR THEORY 22 ■ Multiple echoes Multiple echoes may appear when a short-range andstrong echo is received from a ship, bridge, or break-water. Multiple echoes will appear beyond the target’s trueecho point on the same bearing of a large target. Theycan be reduced with proper adjustment of t...

8 BASIC RADAR THEORY 23 ■ Blind and Shadow sectors Blind or Shadow sectors may exist because of ob-structions such as masts, derricks or stacks. An ob-struction may throw either a complete or partialshadow as shown in the diagram below. If a target is ina shadow sector, target echoes may not appear ...

■ Connecting the units NMEA1 connection NMEA2 connection ■ Power source requirement D DC power source The radar is designed for connection to any powersource if the voltage is 10.2–42 V DC, so that a 12, 24,or 32 V DC battery can be used without a DC-DC con-verter, or any internal modifications. • D...
