The AN / SPQ-9 is a multi-purpose , short range radar. It is used by the US Corporation Systems North produced.

description

The SPQ-9A is able to locate both low-flying airborne and surface targets and provide a fire control solution for the ship's guns and CIWS systems. To interference from clutter and EloGM to avoid the radar can quickly switch between different frequencies (Engl. "Frequency hopping"). There is also an MTI mode and up to 120 targets can be tracked simultaneously ( TWS ). The SPQ-9A is part of the Mk 86 - the fire control system and can be in the " Naval Tactical Data System are integrated" (NTDS).

variants

AN / SPQ-9B

The SPQ-9B is a massive advancement of the SPQ-9A design. The system can now operate independently of other fire control equipment and is integrated into the “ Ship Self Defense System ” (SSDS). The main task of this variant is the detection, tracking and combat of modern, low-flying and supersonic anti-ship missiles , even under massive disturbances from clutter and EloGM. The first devices have been delivered since 2002, and over time all A versions are to be replaced by the B version.
