Donets
Donets is operating in the X-band navigational radar widely fitted both in warships and merchant ships. Donets has a truncated parabolic reflector approx 1.50 m x 0.30 m, with a horizontal rib at the rear.
Donets-2 is a modification of Donets differing in that the parabolic reflector has been replaced by a slotted waveguide with the dimensions of 1.62 m x 0.12 m. The transmitter of Donets-2 has a reduced peak power of 15 kW to achieve a longer magnetron lifetime.
