Don

Don and Don-2 were operating in the X-band navigational radars widely fitted in both warships and merchant ships of former Sovjet Union.

Don has a solid parabolic reflector approximately with the dimensions of 0.6 m x 2.3 m and horizontal polarization. Some models have two small wind vanes on the rear. The minimum detectable range (“blind range”) was 35 m.

Don-2 is a modification of Don differing in that the parabolic reflector is replaced by a slotted waveguide antenna.
