1. OPERATIONAL OVERVIEW Notes on speed input It should be noted that in determining a target's aspect by radar, the calculation of its true track is dependent on the choice and accuracy of the own ship's course and speed input. A ground-stabilized target plot may accurately calculate the ground track of the target, but the target's heading may be significantly different from its track when experiencing set, drift or leeway.

1. OPERATIONAL OVERVIEW 1.20 How to Reduce Sea Clutter Echoes from waves cover the central part of the display with random signals known as sea clutter. The higher the waves, and the higher the antenna above the water, the further the clutter extends. When sea clutter masks the picture, reduce it with the A/C SEA control, either manually or automatically. Note 1: When both sea clutter and rain clutter are reduced, the sensitivity is decreased more than when only one is changed.
1. OPERATIONAL OVERVIEW 1.20.3 How to manually reduce sea clutter A/C SEA control adjusted; sea clutter reduced Sea clutter at screen center Note: The proper setting of the A/C SEA should be such that the clutter is broken up into small dots, and small targets become distinguishable. If the setting is set too low, targets will be hidden in the clutter, while if the setting is too high, both sea clutter and targets will disappear from the display.
1. OPERATIONAL OVERVIEW 1.21 How to Reduce Rain Clutter You can reduce clutter caused by rain, either automatically or manually. Note 1: When both sea clutter and rain clutter are reduced, the sensitivity is decreased more than when only one is changed. For that reason adjust them carefully. Note 2: The echo average function (see section 1.24) is useful for reducing reflections from the sea surface. However, high-speed targets are harder to detect than stationary ones when echo average is active. 1.21.
1. OPERATIONAL OVERVIEW How to fine-tune rain clutter reduction from the on-screen box 1. Select [RAIN MAN], following the procedure in section 1.21.1. RAIN MAN Place the cursor inside the level indication, then spin the scrollwheel. 40 2. While observing the A/C RAIN level indicator, spin the scrollwheel to increase or decrease the level. 100 levels (0-100) are available. Note: The detection range is reduced when the RAIN is used to show targets in rain.
1. OPERATIONAL OVERVIEW 1.22 Interference Rejector Mutual radar interference can occur in the vicinity of another shipborne radar operating in the same frequency band. It is seen on the screen as a number of bright spikes either in irregular patterns or in the form of usually curved spoke-like dotted lines extending from the center to the edge of the picture. Activating the interference rejector circuit can reduce this type of interference.
1. OPERATIONAL OVERVIEW 1.23 Echo Stretch The echo stretch feature enlarges targets in the range and bearing directions to make them easier to see, and it is available on any range. There are three types of echo stretch, 1, 2 and 3, and the higher the number the greater the amount of stretch. Note: The echo stretch magnifies not only small target pips but also returns (clutter) from sea surface, rain and radar interference.
1. OPERATIONAL OVERVIEW 1.24 Echo Averaging The echo averaging feature effectively reduces sea clutter. Echoes received from stable targets such as ships appear on the screen at almost the same position every rotation of the antenna. On the other hand, unstable echoes such as sea clutter appear at random positions. To distinguish real target echoes from sea clutter, echoes are averaged over successive picture frames.
1. OPERATIONAL OVERVIEW How to use the echo average function from the menu 1. Open the menu. 2. Select [1 ECHO]. 3. Select [2 CUSTOMIZED ECHO]. 4. Select [4 ECHO AVERAGE]. 5. Select the required setting. 6. Close the menu. How to highlight fast-moving targets Normally, when echo averaging is in use, fast-moving targets may be displayed weakly, or not at all. The fast target emphasis function highlights fast-moving targets, but can also highlight sea-surface reflections and other noise.
1. OPERATIONAL OVERVIEW 1.25 Automatic Clutter Elimination (ACE) Function This radar has the Automatic Clutter Elimination (ACE) function. This function detects sea and rain clutter from received echoes’ and automatically reduces sea and rain clutter according to the Automatic Clutter Elimination (ACE) threshold setting. Note: Use this function with caution. Weak target echoes may disappear from the screen. 1.25.
1. OPERATIONAL OVERVIEW 1.25.3 How to get high sensitivity When the ACE function is [ON], the high sensitivity mode is also available. High sensitivity mode has three levels ([1], [2], [3]), with [3] applying the highest gain. To use high sensitivity mode, a function key must be assigned with the [ACE HIGH SENSITIVITY] function (see section 1.8). To activate the ACE feature, press the assigned function key. You can select the level of sensitivity for high sensitivity mode as follows: 1. Open the menu. 2.
1. OPERATIONAL OVERVIEW 1.26 Noise Rejector White noise can show itself on the screen as random “speckles” spread over the entire radar image. This equipment reduces the white noise, then improves the on-screen S/ N ratio by processing the weighted moving average filter for the received echoes in the range direction. Note: Use this function with caution. Weak target echoes may disappear from the screen or the range resolution may worsen. To remove this noise do the following: 1. Open the menu. 2.
1. OPERATIONAL OVERVIEW 1.28 How to Preset Controls for a Specific Navigation Purpose Every time your navigating environment or task changes, you must adjust the radar, which can be a nuisance in a busy situation. Instead of changing radar settings case by case, it is possible to assign the function keys to provide optimum settings for oftenencountered situations.

1. OPERATIONAL OVERVIEW 1.29 How to Reject Second-trace Echoes In certain situations, echoes from very distance targets can appear as false echoes (second-trace echoes) on the screen. This occurs when the return echo is received one transmission cycle later, or after a next radar pulse has been transmitted. Pulse interval Actual ranges Second-trace echo Measured ranges This equipment lengthens the pulse repetition period to reject false echoes. Note 1: This function decreases the number of echo hits.
1. OPERATIONAL OVERVIEW 1.30 Orientation Modes This radar has the following orientation modes available: Mode Description Relative Motion (RM) modes [HEAD UP RM] Not stabilized [STERN UP RM]* The radar image is rotated 180°. Graphics and relative and true bearings are also rotated 180°. [STAB HEAD UP RM] Head-up with compass bearing scale (True Bearing) where the bearing scale rotates with the compass reading.
1. OPERATIONAL OVERVIEW COURSE UP mode The radar picture is stabilized and displayed with the currently selected course at the top of the screen. When you change the heading, the heading line moves with the course selected. If you select a new course, select the course up mode again to display the new course at the top of the display. Targets are shown at their measured distances and their directions relative to the set course, which is at the 0-degree position.
