The Selex RAT-31DL is a long-range air surveillance radar manufactured by Leonardo (previously Selex ES, SELEX Sistemi Integrati and later Finmeccanica). The acronym RAT stands for Radar Avvistamento Terrestre, an Italian term for such "ground-based reconnaissance radar".
The RAT-31DL is an L-band solid-state active phased array3D radar with an effective range of over 500 km.[1] It is derivative of widely used RAT-31 SL.
The RAT 31DL is a solid-state active phased array radar with monopulse antenna with 42 rows of 42 Tx/Rx modules of which 24 boosted, each with 2 kW output power. The 360 ° search is performed with four independent beams in the L band at 6 rpm, the vertical pivoting of the beams is done by means of electronic phase shift of the 42 rows feeding the antenna.
RAT-31DL/M
The mobile RAT 31 DL / M radar[1] variant is derived from the stationary FADR version. The RAT 31 DL / M consists of a fold-able antenna and an equipment shelter, which are housed in air transportable 20-foot ISO containers. This configuration allows rapid deployment with high mobility and allows deployment in an unprepared position.
