-2.2- 2.2 Criteria of Tracking A target measuring 800 m or more in the radial or circumferential direction is regarded as alandmass and not acquired or tracked. Echoes smaller than 800 m are regarded as targets tobe tracked. The FURUNO ARPA ATA video processor detects targets in the midst of noise a...

-2.5- 2.4 Entering Own Ship’s Speed The ATA requires own ship’s speed and heading data. Of these, the speed data can be entered automatically from a speed log, navaid or manually through the menu.

-2.15- 2.15 Factors Affecting ARPA Functions Sea returns If the radar anti-clutter control is adjusted properly, there is no serious effect because distant wave clutter, not eliminated by this control, is filtered out by more than one bang correlation and scan-to-scan matching of data. Rain and snow...

-2.16- Indirect echoes A target at close range is usually picked up directly, but it can also be received as reflection from a large, flat surface. This will result in the radar presenting two or more echoes on the display, each at a different range. The ARPA or ATA can acquire and track the false e...
