The Kelvin Hughes Type-1007/8 I-band navigation radar is used by the Qatari, Malaysian, Brunei, Omani, Australian, French, British and Canadian navies.
Through its Sperry Marine subsidiary, Northrop Grumman has supplied its Bridgemaster-E I-band navigation radar to 50 navies worldwide.
Support and Maintenance is also required for the I-Band
Threat Simulator System (TSS) and the Microwave Link.
Additionally, there will be other friendly units, such as surface units, maritime patrol aircraft and the like, as well as offshore oil rigs (usually at I-band radar).
Table 6 describes a limited, generic I-band scenario comprising a number of fishing vessels, merchant shipping and pleasure craft.
In terms of EW systems, Ericsson brings to the table the H-through I-band
Erijammer 200 countermeasures pod together with the Responsive Electronic Warfare Training System (REWTS) family of EW training aids Ericsson has been developing in concert with US contractor Rodale Electronics.
Looking in more detail at a selection of these Nimrod systems, the I-band
Searchwater radar utilizes frequency agility, pulse compression and "smart" processing to maximize target detection in a wide range of sea states.
Cross Systems is installing a ULQ-21-based system for the I-band
jammer, the heart of the Type 4 jets.
4-GHz/2- to 18-GHz BM/KJ 8502 fixed-wing RWR, the BM/KG 8601 E/F- and I/J-band repeater jammer, the BM/KG 8606 I-band
radar jammer, the BM/KG 8605 I/J-band noise jammer and the BM/KG 8605 I-band
The chief EC tool is the ALQ-176 radar jammer, which can counter D-,E/F- and I-band radars using spot and barrage modes.
The suite used comprises an internalized Lundy ALE-43 D-,E/F- and I-band chaff dispenser and an active jamming subsystem made up of Rockwell-Collins UST-104 (VHF/UHF communications), Rodale DLQ- 3C (I-band fire control/air intercept radars) and Hercules ALQ-176 (D-, E/F- and G-band surveillance radars) transmission units plus fore and aft radar receivers.
While no equipment sources have been formerly identified, JED understands that the radar jammer will be a Cross Systems equipment which is based on the AN/ULQ-21, covers the C-through G- and I-bands
and features 16 prestored techniques, in-flight programming and 16 emitter profile sets for its associated set-on receiver (see "New Life for Contractor Training Flight Services," JED, January 1993, p.
