The 3-in-one Variant radar, offers surveillance and target indication. Its principal role is as an automatic, fast reaction time radar sensor, supplying targeting data to weapon systems. Automatic target detection and tracking in 2D plus radial speed is supplied for both air and surface targets simultaneously. For surface targets, it offers 3 gunfire channels.
Variant includes a dual-band radar, utilising both the I- and G-bands (X&C-band). Fully coherent, Variant provides pulse-doppler operation for optimal clutter suppression and air target detection without disturbance by multi-path (or lobbing) effects thanks to the dual-frequency. Outstanding ECM facilities are provided by the ability to operate over two frequency bands, an octave apart, and the third part of Variant, an integral Low Probability of Intercept (LPI) radar. This LPI radar (see also entry: Scout) can be used alone, thus providing Variant the unusual ability to operate in a mode that is almost undetectable to external ESM.
Variant's low power consumption, lightweight construction and compact design, make the system well suited for use on fast patrol boats and OPVs. For larger ships that need helicopter/UAV guidance, it's the radar of choice, due to it's extreme short minimum range.
