6. RADAR
6-17
6.19 Dual-Range Display
The dual-range display scans and displays two different radar ranges at the same
time, with a single antenna. There is no time delay between the two pictures and, with
the magnetron radar, you have separate control of each picture. (The solid state radar
has some restrictions. See the table below for details.) This feature lets you keep a
close watch on close-range targets and far targets.
Note: Radar sensor DRS4DL does not have the dual-range display.
To get the dual-range display, set dual-range displays on the home screen. See
paragraph 1.7.1 for the procedure. You can put the dual-range displays in the two-way
and three-way split screens.
Most radar functions can be adjusted independently. The table below shows radar
function and operability in the dual range mode, for both the magnetron radar and the
solid state radar. Note that, in the worst case, the maximum detection range may de-
crease by approx. 10 dB with the solid state radar.
* Cannot be adjusted when the Target Analyzer (radar sensor DRS4D-NXT) is active.
