Advanced mission capabilities provided with the Gripen NG AESA Radar
Improved Target Tracking
With the inherent beam agility, target tracking
can be more adaptive and time efficient. This
will increase the radar tracking performance in
a dense target environment. This facilitates the
ability to choose the right target for weapon
engagement, and to prepare the weapon with
more accurate data i.e. enhance the fire control
capability.
The beam agility will also increase the capability
to perform search for new targets within a larger
search volume while retaining the target track
updates for current tracks. This will increase the
pilot’s situation awareness.
Wide field of regard
With the swashplate solution the Gripen NG
AESA radar has the ability to cover a scan angle
up to ±100°. This will increase situation awareness
and be used to increase the quality of SAR
images.
In BVR combat, wide angle scan also
allows the aircraft to maintain track on the target
whilst executing a 90° manoeuvre. This minimises
closure rate with the target, places one’s own aircraft
in the enemy’s clutter return and still allows
full guidance of BVR missiles.
Mode Flexibility
With the beam agility it is possible to interleave
different modes. This capability further increases
the situation awareness for the pilot. For example,
the pilot can use Air-to-Ground modes in parallel
to Air-to-Air search and track.
Low Probability of Intercept
The AESA radar has qualities that makes the
aircraft more difficult to detect by an enemy and
thereby increases the aircrafts survivability. These
qualities include lower radar cross section, ability
to operate with reduced output power levels
and side-lobe levels, and the agile beam used for
random search and track patterns.
Flexible beam and waveform control makes it
possible to optimize modes for long and short
range target acquisition. The AESA system is
also able to be cued by other onboard sensors,
eg Infra-Red Search and Track (IRST) or by data
from off-board resources such as Erieye. This will
increase the pilot’s situation awareness and make
it possible to take action earlier.
Improved Electronic Counter-
Counter Measures
Future adaptive beam forming facilitate improved
target detection in presence of several jammer
signals. Situation awareness can then be maintained
even in a dense RF-environment. This is
important for survivability.
Increased Operational Availability
The modular design of the antenna, including
the large numbers of transmit/receive modules,
ensures graceful degradation. This means that the
antenna will maintain excellent performance even
with a percentage of failures. This ensures high
availability which is an essential pre-requisite for
high intensity operations.
