1. Fundamentals of Radar
1.1. Definition
1.1.1. Radar, an acronym for "Radio Detection and Ranging," is a technology that uses electromagnetic waves to identify the range, angle, or velocity of objects. The fundamental principles of radar revolve around the transmission of radio waves and the subsequent analysis of their reflections from objects.

2.2.1.1. Antenna
2.2.1.1.1. The E/F-Band Antenna is a 12ft array which rotates at 22/26 rpm and is bolted directly to the pedestal. It has a Peak Power of 30KW and an Intermediate Frequency of 60 Mhz. Producing a horizontal beam width of 1.9deg and a vertical beam width of 23deg.
2.2.1.2. Pedestal
2.2.1.2.1. THe pedestal, whic in turn are mounted directly to the ship's structure either on the twd section of the mainmast or the hangar roof.
2.2.1.3. Modular Transmitter Reciever
2.2.1.3.1. The task of each transceiver is to filter and amplify the receipted signal and to convert the received microwave signal into signal format for coaxial cable. It also controls the pedestal (antenna) depending on rotation and pulse length for radar signal transmission.
2.2.1.4. Man Aloft Switch
2.2.1.4.1. A Man Aloft Switch prevents a radar transmission and rotation during a maintenance or repair at the radar antennas or nearby. For the fwd I-band and E/F-band radars the switches are located in the NAV & EOSP equipment room (03E), and for the aft I-band radar it is fitted in the QM/FDO Cabin at (1K-B3).
