AN/SPQ-9

The AN/SPQ-9 is a multi-purpose, short-range radar. It is produced by the U.S. company Norden Systems.

Description

The SPQ -9A is able to locate both low-flying air and surface targets and provide a fire control solution for the naval guns and CIWS systems. To avoid interference from clutter and EloGM, the radar can quickly switch between different frequencies ( engl. "frequency hopping" ). Further, a MTI mode present and up to 120 aims simultaneously (TWS ). The SPQ -9A is part of the Mk - 86 fire control system and can be integrated into the " Naval Tactical Data System " ( NTDS ).

Variants

AN/SPQ-9B

The SPQ -9B is a massive development of the SPQ -9A designs. 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 control of modern, low-flying supersonic anti-ship missiles and even under massive interference from clutter and EloGM. Since 2002, the first units are delivered, it should all A variants are replaced by the B version over time.
