RTN-30X “Orion”
The RTN-30X alias MM/SPG-75 (MM stands for Marina Militare, a nomenclature for the Italian Navy, similar to the US-Army/Navy's nomenclature AN/…) is an operating in I-Band fire-control and missile guidance radar.
The radar uses a monopulse, cassegrain antenna with a polarisation twist and employs a fully coherent chain transmitter using a traveling wave tube as the final amplifier. Two operational modes can be selected: a long pulse mode and coded waveform with pulse compression with 13-bit Barker code, and a short pulse mode using a keyed on/off single pulse with the length of 0.5 µs. The fully digital receiver uses a multicanceller moving target indicator and is equipped with devices to minimise the effects of multipath on low-flying targets.
The RTN-30X has many components in common with RAN-30X surveillance radar.
