    The minimum range depends on the pulselength, antenna height, and signal process- ing (like main bang suppression and digital quantization). Use a shorter range scale as far as it gives favorable definition or clarity of picture. This MODEL 1835 series meets the requirements of IEC 62252 5.14.1 (Class A).

  • Page 73: Radar Resolution

    2. DESCRIPTION OF RADAR 2.1.2 Radar resolution The bearing resolution and range resolution are important in radar resolution. Bearing resolution The bearing resolution is the ability of the radar to display the echoes received from two targets at the same range as the separate echoes. The bearing resolution is pro- portional to the antenna length and the wavelength.

  • Page 74: Bearing Accuracy

    2. DESCRIPTION OF RADAR 2.1.3 Bearing accuracy One of the most important features of the radar is how accurately the bearing of a tar- get can be measured. The accuracy of bearing measurement depends on the narrow- ness of the radar beam. The bearing is taken relative to the heading of the ship. Correct adjustment of the heading line at installation is important to get accurate bear- ings.

  • Page 75: Sidelobe Echoes

    2. DESCRIPTION OF RADAR 2.2.2 Sidelobe echoes When the radar pulse is transmitted, some radiation escapes on each side of the beam, called "sidelobes”. If a target is where a target can be detected by the sidelobes as well as the mainlobe, the side echoes can be shown on both sides of the true echo at the same range.

  • Page 77: Sart (Search And Rescue Transponder)

    2. DESCRIPTION OF RADAR SART (Search and Rescue Transponder) 2.3.1 SART description When any X-band radar reaches within a range of approximately 8 nm, a Search and Rescue Transponder (SART) sends a response to the radar signal. The transmitter signal of response is 12-sweeps signal between 9,500 MHz to 9,200 MHz. The time of slow sweep signal is 7.5 μs and the time of fast sweep signal is 0.4 μs.

  • Page 78: General Remarks On Receiving Sart

    2. DESCRIPTION OF RADAR 2.3.2 General remarks on receiving SART SART range errors When the SART is at a range greater than approximately 1 nm, the first dot is dis- played at 0.64 nm beyond the true position of the SART. When the range closes so that the fast sweep responses are seen also, the first range echoes are displayed at 150 m beyond the true position.

  • Page 79: Racon

    2. DESCRIPTION OF RADAR RACON A RACON is a radar beacon which emits radar-receivable signals in the radar frequen- cy spectrum (X- or S-band). There are several signal formats; in general, the RACON signal appears on the radar screen as a rectangular echo originating at a point just beyond the position of the radar beacon.
