1.	Which of the following is responsible for the reduced use of transmitter power in radar altimeter?(a) Low range(b) Interference with other bands(c) Receiver low noise amplifier(d) Radome
Answer» The correct option is (c) Receiver low noise amplifier To elaborate: The transmitter power depends on the sensitivity of the receiver. The receiver low noise amplifier typically has a 2 to 3 dB noise figure, resulting in a sensitivity level that allows relatively low transmitter power.
