  • Page 171: Radar Shadow

    MDC-2900 Series Chapter 6 Principle 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 172 Chapter 6 Principle of radar system MDC-2900 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.

    MDC-2900 Series Chapter 6 Principle 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.
