MDC-2000A Series Chapter 5 Installation Chapter 5 Equipment 5.1 Antenna Installation Determining the location of the installation The search capability of the radar varies largely, depending on the position of the antenna installation. The ideal installation position is the high place over the keel line where no obstacle surrounds. Actually, though there are many limitations in a ship, determine the installation position, considering the following items. 1.
Chapter 5 Installation MDC-2000A Series How to shift the antenna from an obstacle 1. How to shift the antenna from the keel line By shifting the antenna from keel line to the starboard, the blind moves to the port and the visibility in the heading can be secured. According to a distance to an obstacle, the distance to be shifted can be derived from the formula below.
MDC-2000A Series Chapter 5 Installation Installation of Antenna After determining the location of the installation, install the antenna. When installing, if the bracket shown below is available, the installation is easier. If not available, install the antenna directly on the roof, paying attention to the air tube for drain at the bottom of the antenna. Note: If the radar mast or installation bracket is warped more than 2mm, make it flat or adjust by inserting spacers.

MDC-2000A Series Chapter 7 Principle of radar system Chapter 7 Principle of radar system 7.1 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.
Chapter 7 Principle of radar system 7.2 MDC-2000A 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. Sight line D(NM)=2.
MDC-2000A 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. On the display, one image appears with a right distance and bearing, and another one appears in the direction of chimney stack, mast, etc.
Chapter 7 Principle of radar system MDC-2000A 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. If a large target such as land exists near your ship, a circular arc shaped image may appear.
