The airborne
defense suite TALISMAN

Application
The airborne defense suite (ADS) Talisman is intended for aircraft protection against:
 all types of guided Air-to-Air (AAM) and Surface-to-Air (SAM) missiles fitted with active(semi-active) radar seekers;
 all types of guided Air-to-Air and Surface-to-Air messiles fitted with electro-optical (IRand semi-active laser) seekers;
 ground-based air defense systems, employing command-guided SAMs.
The ADS Talisman also ensures aircraft protection against the ‘friendly fire’ of air intercept
missile systems as well as ground-based air defense systems.

Design and Installation Variants
The ADS Talisman may be either pod-mounted or installed conformally provided there issufficient inner fuselage space available in aircraft. The pod-mounted variant of the ADS
Talisman is housed in two small-size pods with them to be mounted on the under-wing
weapon stations of the carrier and spaced apart for the maximum distance possible (up tothe wing tips).
The pylon design of the pods provides for the suspension of the air launchers, which allows
for the Talisman ADS- carrier to preserve its standard aircraft weapons (keeping theweapon stations ‘vacant’).
The effectiveness of the aircraft protection in the forward and rear hemispheres with theADS Talisman amounts to 0.9 and higher.
The protection effectiveness is understood to mean the probability of the ADS Talismancarrier not to be engaged by guided missile weapons.
All the equipment of the ADS Talisman is housed in two pods.

Missile Approach Warning RadarElectronic Protection Equipment
Electronic protection equipment (EPE) ensures the individual protection of the host aircraft
based on the reemission of the hostile RES (radio electronic system) probe signals withthem being provided with the particular phase, frequency, amplitude and polarization
modulation. RESs are understood to mean:
 fighters’ on-board radar sighting systems (RSS); target attack radars of SAM-systems;
 active radar seekers (ARS) of the guided AAMs and SAMs;
 semi-active radar seekers of the guided AAMs and SAMs.

Electronic Protection Equipment
The modulated reemission in each hemisphere simultaneously together with the echo
signal from the carrier air-frame (the one of the aircraft under protection) results in thewave front distortion, perceived by the antenna systems of the hostile RESs, thus exertingan all-inclusive impact on angle, range and velocity (Doppler) measuring instruments as wellas the tracking systems of the hostile RES. This impact shows in the form of stable false
targets (marks) substantially spaced from the true range, Doppler, azimuth and elevation
coordinates of the aircraft under protection.
False targets perform guided maneuvering, thus simulating the flight of the real target.
At the same time any changes in the probe signal’s parameters such as carrier frequency,
pulse width and pulse repetition frequency, the modulation type and the power level of theemitted signal of the jammed hostile RES are immediatly registered.
The jamming impact happens to be concealed at the signal level and is not detected bystandard ECCM equipment and the one for jamming analysis.
The impact of the EPE on the suppressed RESs is ensured at all stages of the RES operation.

Apart from radar warning, the ADS Talisman provides a possibility to analyze theeffectiveness of impact on the jammed RES. The analysis is executed by monitoring theresponse of the jammed RES to the jamming impact. The results of the current
effectiveness monitoring are displayed to the pilot of the aircraft under protection directlyin the course of the flight in real time.
The given data are registered by the in-built flash-storage device and may be studied afterlanding.

Missile approach warning radar (MAWR)
MAWR is intended to notify the crew of the guided missiles (with any types of controlsystems) approaching in the forward and rear hemispheres. Protection against electrooptical guided missiles is gained by means of the time (range, angle sector and automatic or
automated anti-missile evasive maneuvering) optimization of flare dispensing.
Main advantages
Automatic (with no pilot/ operator input) jamming generation against all hostile illuminating
RESs
No restrictions on the number of the simultaneously jammed on-board
and ground-based RESs
Total exclusion of the ADS-carrier self-radiation
The employment of the ADS places no restrictions on the air combat tactics of the aircraft
under protection
When in close formation, the ADS-carrier securely covers a friendly neighbouring aircraftwith no EAE (electronic attack equipment)
Full electromagnetic compatibility with the self radio electronic equipment (the one of theaircraft under protection), including the on-board radar, as well as the compatibility withthe on-board radar of the neighbouring aircraft in formation

Operational reliability
The operating condition of the ADS is monitored during the pre-flight checks as well asdirectly in the course of the flight. The in-built test system ensures the walkthrough of theequipment operability, as well as detection and localization of the equipment failure within
the accuracy of the block.

Installation
The ADS Talisman may be installed on any type of the aircraft with the minimum retrofit of
the on-board equipment. The aircraft board retrofit includes the installation of the control
and display panel in the cockpit, as well as the installation of the HF and LF cables inside thewing and fuselage. The retrofit of the aircraft board may be executed at the aircraft repair
facility or in the field. For the aircraft fitted with interfaces 1553 or 1760 (MIL STD- 1553,
MIL STD -1760) the connection of the ADS is carried out through the interfaces, mentionedabove.
