    MDC-7000/7900 Series Chapter 8 Principal of radar system Chapter 8 Principal of radar system What is radar system? The radar is a navigation device that transmits a very high frequency radio wave referred to as microwave from the 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 172: Beam Width

    Chapter 8 Principal of radar system MDC-7000/7900 Series Beam width Antenna beam width is defined as the angle where the radiation power density is within a half of maximum power density (-3 dB) in main lobe (also, referred to as “half value width”). Characteristics of radar radio wave The radar radio wave propagates slightly along the ground (primarily line of sight).

  • Page 173: Radar Shadow

    MDC-7000/7900 Series Chapter 8 Principal of radar system Radar shadow Since radar radio wave is line of sight in nature your stack mast close to the antenna or, a large ship or mountain may create blind spots for which the radar cannot penetrate. In such cases, they may completely or partially hide targets and cast a long shadow.
  • Page 174 Chapter 8 Principal of radar system MDC-7000/7900 Series ● Duplicate target images When there is a big reflective surface nearby and it is perpendicular at a close distance (i.e. when your ship is passed by a big ship, etc.), the radio wave bounces between own ship and the other ship. Therefore, two to four images may appear at equal range in the direction of this target.

  • Page 175: Radar Interference

    MDC-7000/7900 Series Chapter 8 Principal of radar system ●Skip target images False image of a distant target caused by “skip” phenomenon Depending on weather conditions, skip caused by the temperature inversion layer of air, etc. may appear. In this case, the radio wave may unusually propagate to distant targets out of the radar range. A target at more than the maximum range may appear as an image, and may be displayed as a false image with closer distance than the actual one.
