Zarya

The Zarya was a maritime surveillance and target assignment radar operating in J-Band for the control of ship artillery and torpedoes on cruisers and destroyers.

The radar was developed between 1947 and 1949 and was taken into the armament of the Soviet Navy from 1950.

A further development with an organ pipe scanner for target tracking was called Zarya-chaika (cyril. «Заря-Чайка»). This version was also used as coastal protection radar in the inventory of artillery forces with the caliber from 100 to 155 mm. The feed horn of this organ pipe scanner rotated at 17 revolutions per second and produced a beam sweep of ± 4°. This enabled automatic target tracking.
