The HR-76 is an operating in I-Band solid-state fire control radar with combined search, detection and tracking capabilities. It can be mounted on small, high-speed patrol craft or be employed by larger vessels.
The radar consists of antenna and antenna pedestal, transmitter, receiver, the computer and signal processing subsystem, and the command and control console. The antenna is a lightweight four-horn monopulse cassegrain unit with a diameter of 1 m. The transmitter employs a vacuum tube modulator allowing multiple waveforms; other transmitter features include multiple pulsewidths and multiple jittered pulse repetition frequencies.
