Assessing the Tikhomirov NIIP L-Band Active Electronically Steered Array
Tikhomirov NIIP in Moscow are developing an L-band AESA radar system intended for embedding in the leading edges of fighter wings. A demonstrator of the L-band AESA subsystem was publicly displayed at MAKS2009.
This paper analyses the operational potential of this design, and performs a range of performance estimates based on manufacturer disclosures and known design features.
The design has clear potential to provide a genuine shared multifunction aperture with applications including:
1. Search, track and missile midcourse guidance against low signature aircraft.
2. Identification Friend Foe / Secondary Surveillance Radar.
3. Passive angle tracking and geolocation of JTIDS/MIDS/Link-16 emitters at long ranges.
4. Passive angle tracking and geolocation of L-band AEW&C/AWACS and surface based search radars at long ranges.
5. Passive angle tracking and geolocation of hostile (i.e. Western) IFF and SSR transponders at long ranges.
6. High power active jamming of JTIDS/MIDS/Link-16 emitters.
7. High power active jamming of satellite navigation receivers over large areas.
8. High power active jamming of L-band AEW&C/AWACS and surface based search radars at long ranges.
9. High power active jamming of guided munition command datalinks over large areas.
Performance modelling for a range of feasible configurations indicates the radar will deliver tactically credible search range performance.
The Tikhomirov NIIP L-band AESA is an important strategic development, and a technology which, once fully matured and deployed in useful numbers, will render narrowband stealth designs like the F-35 Joint Strike Fighter and some UAVs, highly vulnerable to Flanker variants equipped with such radars.
