D. Jammer pursuit , “PB”
In “HA” and “lC” function, a jammer detected during the search is displayed on the scope by two
vertical line markers that frame the direction of the jammer.
The two markers are more distant from each other the closer or the more powerful is the
jammer.
E. Ground visualization, “V1”
When viewing the ground, the electrical beam of the antenna explores the terrain in front of the
aircraft by sweeping 60° or 30° on either side of the radar axis. This scan can be in two or one
elevation lines depending on the scale selection.
The echo density is changed using the gain control.
6- Scale selection
Four distance scales are available to the pilot. This scale selection is done according to the target
echo distance by means of the control on the radar control stick base at the rear.
Markers appear on the scope depending on the selection.
4 amber lights on the right of the radar indicator indicate this selection. Each LED indicates the
displayed scale.
Scales 60 NM 35 NM 15 NM 7NM
Respective marker distances 10 NM 10 NM 5 NM 2NM
A. In "HA" and “IC” functio ns
These four scales are usable.
NOTE: If the "HA" and "IC" functions are selected, when selecting 530 (with an EM missile), the
scale automatically switches to 35 NM when the scale selector is on "60".
B. In “V1”
The 60 and 35 NM scales provide a two-line scan. The upper row tilt (left to right) is a function
of the airplane altitude given by the aerodynamic unit; it is such that, when the displayed tilt is
zero, the intersection of the scan plane with the horizontal plane of the terrain overflown is at
an oblique distance of 24 NM. The tilt of the lower line (right to left) is a function of the first. The
correction that the pilot can add to the tilt of the upper line is approximately ± 1°.
The 15 and 7 NM scales provide a scan, at one elevation line, displayed by the pilot within the
limits of ± 6°30'. The displayed tilt defines in hundreds of feet a fictitious horizontal plane that
the radio-electric axis intercepts at a constant distance of 9 NM (15 NM scale) or 4 NM (7 NM
scale).
C. In "TL" and "BZ"
Only the 7 NM scale is in service.
7- Alidade (strobe)
It is a segment appearing on the scope and whose brightness is adjustable by the "AL"
potentiometer of the indicator scope control box. It allows the pilot, by positioning the alidade
on the chosen and engaged echo, to define the bearing and the distance of this echo and to
predetermine, for the radar computer, the average bearing of the antenna. The alidade is
controlled in bearing by the lateral displacement of the radar stick around its longitudinal axis;
