Product Profile of Radar Aid For Surveillance And Harbor Maneuvering In I Band

Bharat Electronics offers Radar Aid for Surveillance and Harbor Maneuvering in I band. PIN 524. The product Radar Aid for Surveillance and Harbor Maneuvering is designed as Navigational radar because of the increase in ocean traffic and congestion in and around harbor. Radar Aid for Surveillance and Harbor Maneuvering is a fully solid-state, hi-tech device. Radar Aid for Surveillance and Harbor Maneuvering is ruggedised one. The special feature of the Radar Aid for Surveillance and Harbor Maneuvering include the BITE facility, which enables one to have a quick check of the radar`s health and the use of a RF Low Noise amplifier [LNA] at the receiver front end greatly enhances the detection probability of weak echoes. Radar Aid for Surveillance and Harbor Maneuvering consists of parabolic antenna with pedestal, Transmitter-receiver, Auxiliary unit, 18.1 Flat panel LCD color display. A second display can also be used with a provision to designate either of the displays as Master display. Radar Aid for Surveillance and Harbor Maneuvering has Sector control unit, Remote control unit and Man aloft Switch. The salient features of the Radar Aid for Surveillance and Harbor Maneuvering:

• Parabolic antenna with circular polarization facility to reduce rain clutter
