2-1 2. RADAR OBSER V A TION 2.1 General 2.1.1 Minimum and maximum ranges Minimum range The minimum range is defined by the shortest distance at which, using a scale of 1.5 or 0.75 nm, a target having an echoing area of 10 m 2 is still shown separate from the point representing the antenna position.
2-2 X-band and S-band In fair weather , the above equation does not give a significant difference between X- and S-band radars. However , in heavy precipitation condition, an S-band radar would have better detection than an X-band radar .
2-3 2.2 False Echoes Occasionally echo signals appear on the screen at positions where there is no target or disappear even if there are targets. They are, however , recognized if you understand the reason why they are displayed. T ypical false echoes are shown below .
2-4 2.2.3 V irtual image A relatively large target close to your ship may be represented at two positions on the screen. One of them is the true echo directly reflected by the target and the other is a false echo which is caused by the mirror effect of a large object on or close to your ship as shown in the figure below .
2-5 2.3 SART (Search and Rescue T ransponder) A Search and Rescue T ransponder (SAR T) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 nm. Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band.
2-6 2.3.2 General remarks on receiving SART SART range errors When responses from only the 12 low frequency sweeps are visible (when the SAR T is at a range greater than about 1 nm), the position at which the first dot is displayed may be as much as 0.
2-7 A/C RAIN control This should be used normally (to break up areas of rain) when trying to detect a SART response which, being a series of dots, is not affected by the action of the anti-clutter rain circuitry . Note that Racon responses, which are often in the form of a long flash, will be affected by the use of this control.
