  • Page 78: Chapter 7 Principle Of Radar System

    MDC-2000 Series Chapter 7 Principle of radar system Chapter 7 Principle of radar system What is the radar system? The radar system is a navigation device that transmits a very high frequency radio wave referred as microwave from antenna. The radar then receives the radio wave reflected by target(s) (e.g. other ship, buoy, island, etc) via the same antenna and converts the received radio wave to electronic signals and sends these signals to the Display unit.

  • Page 79: Characteristics Of Radar Radio Wave

    Chapter 7 Principle of radar system MDC-2000 Series Characteristics of radar radio wave The radio wave propagates slightly along the ground (primarily line of sight). This characteristic varies depending on the density of atmosphere but generally calculated according to the formula as shown below, considering that the distance with radar sight D is about 6% longer than the distance with optical sight.
  • Page 80 MDC-2000 Series Chapter 7 Principle of radar system ● Virtual image The image of a large physical object in a close proximity may appear in two different orientations. One is a real image and the other is a false image caused by wave reflected on the chimney stack or the mast, etc.

  • Page 81: Radar Interference

    Chapter 7 Principle of radar system MDC-2000 Series ● False image by sidelobe The microwave beam radiated from the antenna has a side lobe in different direction than that of the main beam. Since this side lobe is lower than that of main beam, the effect is negligible for targets at a long range, but a close, strong reflecting target may cause false image in a circular arc shape.
