DA 01

The DA 01 (abbreviation of Dutch words: Doels Aanwijzing, i.e. target indication) was an operating in S-Band air and sea surveillance radar for medium-range surveillance and target indication. The low weight of the antenna system enables installation in smaller ships.

The antenna is a parabolic reflector fed by an H-plane Sectoral Horn. It provides a Cosecant squared pattern. The transmitter used a magnetron.
