|The AN/SPQ-9 Surface Surveillance and Tracking Radar,
developed by Northrop Grumman Norden Systems, Melville, NY, is a
track-while-scan radar used with the MK-86 Gunfire Control system on
surface combatants. It detects sea skimming missiles at the horizon even
in heavy clutter while simultaneously providing detection and tracking
of surface targets and beacon responses.
The upgraded SPQ-9B - which
uses a high-resolution, track-while-scan,
The AN/SPQ-9B antenna provides for three beams. If an air target is detected in the main beam, two look-back beams provide confirmation and track promotion resulting in "single-scan" track disclosure to a ships weapon system.
