3.18 RADAR
Description
The Mirage F1CE is equipped with the CYRANO IV on-board fire control radar.
It has a maximum range of 60 NM in search mode, and 35 NM in lock-on mode. It incorporates
antijamming circuits for passive directional tracking. The antenna platform is slaved to the
horizontal position, provided that the aircraft roll angle is less than ±80°.
Radar functions

Interception
It includes:
o
search that leads to the detection of the target
o
engagement, in distance and in direction, of a selected target
o
automatic pursuit phase which makes it possible to bring the aircraft into a firing
position or to carry out a blind rendezvous
o
manoeuvring phase after firing.

Close combat functions “TL” and “BZ”
These functions allow the radar to lock automatically a target located at a distance of
less than 7 km.
They have priority over all other functions.
They are also divided into phases, which are:
o
search during which the radar scans ahead of the aircraft from 400 m to 7000
m
o
engagement on the first target found in the distance
o
automatic pursuit

AIR-GROUND function
In this function, the indicator scope presents the radar map of the terrain in front of the
aircraft.
Four distance representation scales are available to the pilot: 60, 35, 15 and 7 NM.
The mean bearing position is zero and the radio-electric beam explores a sector of ± 60°
or ± 30° in bearing centered on the aircraft axis.
The elevation is a function of the altitude of the flight (in the scales 60 and 35 NM) and
can be modified to better illuminate the area of terrain overflown and obtain a usable
representation on the scope.
