Ramses, Scimitar, SLQ-503 ECM family RAMSES (Reprogrammable Advanced Multimode Shipborne ECM System) is a modular naval electronic countermeasures system designed principally to provide protection for ships against I/J-band (8 to 18/20 GHz) radar threats. It is an integrated responsive jammer capable of long-range jamming of search radars and the deception of missiles once launched. The system's normal mode of operation is to be connected to, and controlled by, the ship's combat control system, thus removing the need for a dedicated system operator. It is also capable of being connected directly to, and controlled by, the ship's electronic support measures system to provide an integrated electronic warfare solution. RAMSES operates in I/J-band and is capable of high-pulse and continuous wave effective radiated power. Multimode jamming operation is possible with multi-target handling capability. The system is reprogrammable and power management is provided. The antennas are fully trainable (port and starboard each through 180') and are stabilised for roll and pitch.
