Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3 Theory of Operation This chapter gives additional information about Radar operation and functions. It explains terminology and describes a number of effects which have influence on Radar performance and have to be considered by the operator. A Radar uses a very high frequency radio wave (microwave) which has similar properties to those of light regarding straightness and uniform velocity.

Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2 Radar Pattern Interpretation The Radar displays a chart- like picture (PPI) on TFT under normal conditions. Under certain conditions, however, various false echoes are generated, and small targets are hidden by rain, snow or sea waves. To correctly interpret targets and patterns which appear on the TFT requires considerable experience.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2.1.1 Sea Clutter, Rain Clutter The Radar wave is reflected by waves, clouds, rain and snow. This is displayed as a bright noise which clutters the Radar Video and may hide targets When this happens, adjust GAIN, SEA (sea clutter), RAIN (rain and snow clutter) controls to assist in the detection of targets. Then adjust FTC. Take note that ordinary visible targets cannot be seen in heavy rain and snow (Figure 3-4).
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2.1.2 Interference Effect Under certain conditions (e.g. if the interference is nearly synchronous with the own transmit pulse), the transmitted electromagnetic waves of Radar systems from other ships can lead to interferences with own Radar. In that unlikely case slowly moving spotters or spirals can be observed on the PPI. The Radar processing removes these interferences automatically if IR ON is activated (Figure 3-5).
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2.1.3 Side Lobe Effect In short ranges, not only the main lobe of the Radar is reflected by ships nearby but in some cases also the side lobes are reflected. This leads to false echoes, which are all at same distance, but different bearings. Multiple reception effect.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2.1.4 Second trace false echo The second trace false echo appears when the signal is received at the next pulse repetition period after it was reflected by a high mountain or similar object in long distance. Therefore, the position in which it appears is identified by subtracting distance corresponding to the pulse repetition interval from the actual distance.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual It often appears that the radio wave propagation is abnormal (duct effect), when the object is a very large mountain. If the signal reception level, however, is small and the transmitted pulse intervals are slightly changed, then a long cloudy form echo appears as shown in the figure, and can easily be identified. If it is difficult to identify, reduce the receiver gain (GAIN) slightly. In rare cases, the guard ring alarm goes off.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.2.1.5 Abnormal Atmospheric Conditions Under certain abnormal atmospheric conditions, the Radar wave can be reflected at higher layers in the atmosphere. This leads to wrong measurements in long distances. Invisible range Visible range Atmosphere Figure 3-9 4265.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.3 Vector Presentation 3.3.1 True Vector Mode True vector mode displays the true movement of all targets with true course and true speed. The actual speed and course of own ship and two targets are such that target 1 will eventually collide with own ship, and the target 2 will pass well behind own ship. In TRUE vector mode, tracked targets which are standing still (such as target 3) do not display a vector.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.3.2 Relative Vector Mode Relative vector mode shows how targets move in relation to own ship. All ships that have relative vectors pointing to my own ship are dangerous targets. Figure 3-11 Relative Vector Mode When the same situation is displayed in RELATIVE vector mode, target 1 is gradually closing with own ship and it is apparent that target 2 indicates no threat as long as neither own ship nor target changed their headings.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.4 Automatic Radar Plotting Aid (ARPA) The purpose of an Automatic Radar Plotting Aid (ARPA) is to interpret Radar information continuously and to display the results so that watch officers may quickly assess and react to potential danger. The performance specification of the International Maritime Organization (IMO) requires the ARPA plotting reliability to be as good as manual plotting techniques.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.4.1 Sensor Errors The performance of ARPA depends on the quality of the sensor information which is processed. The Radar is the sensor which measures target range and bearing relative to own ship. The gyro compass measures the heading of the own ship relative to north. The speed log measures the motion of own ship relative to the water or bottom. 3.4.1.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual (2) COAST Option: The lost target data is not automatically cancelled but rather is “coasted “ and the flashing LOST TARGET symbol marks the last position of the target. To delete the LOST TARGET symbol, track, and target data, a manual cancel operation must be done. CAUTION If the target gets close to another target, the two targets cannot be discriminated and tracking may resume on these signals. The operator should investigate all ARPA Alarms.
Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.4.2 Collision Assessment (Surveillance) Once the true velocities of own ship and targets are established (within one minute of acquisition), it is valid to interpret displayed information for collision assessment. TRUE and RELATIVE VECTORS are available to present target velocities. The NSC provides two additional surveillance features to aid in rapid assessment of collisions potential in congested situations.

Synapsis Radar with Nautoscan NX Pedestal Operator Manual 3.5 Keep the Following Points in Mind when Operating the NAUTOSCAN NX • Radar Video The Radar video display area is updated from a memory. The memory is updated as the antenna scans. The Radar picture is signal processed from previous scan of the antenna. This process is called scan-to scan correlation. Three scans are required to integrate a target to full brightness.
