W-160 is operating in the I-Band shipborne multifunction naval radar. The primary functions of the W-160 are the generation of accurate track data for effective fire-control and target illumination radar for surface-to-air missiles.
The W-160 employs technology developed for the AN/APG-66 and AN/APG-68 families of airborne fire-control radars. The W-160 consists of an antenna assembly and two equipment cabinets. The antenna assembly contains the parabolic antenna with a diameter of 1.22 m, using a monopulse horn feed with vertical polarization, pedestal and radome. The transmitter uses a Traveling Wave Tube. The receiver uses pulse compression with a compression ratio of 13:1 and a moving target indication with a 3-pulse canceller and an improvement factor of 57 dB.
