1.	A power of 5 kW to 50 kW is required even when using narrow beams.(a) True(b) FalseI have been asked this question at a job interview.This interesting question is from Traffic Alert, Collision Avoidance System & Weather Radar topic in division Surveillance Systems, Mapping and Multimode Radars of Avionics
Answer» The correct choice is (a) True To explain: Even with narrow beamwidth antennas, the RADAR TRANSMITTER requires from 5kW to 50KW of output power. When coupled with an antenna of 25 dB, this combination can result in an EFFECTIVE power more than a million watts.
