Which component is responsible for transmitting the radar pulses in a radar altimeter system?

• A. Height Indicator.
• B. RADAR Altimeter Antenna.
• C. Mission Computer.
• D. Electronic Altimeter Receiver-Transmitter.

Answer: (D)

This question focuses on which part actually generates the radar pulses in a radar altimeter. In radar systems, a transmitter creates the RF pulses and sends them through the antenna, while the receiver captures the echoes to measure the time it takes for the pulses to return. The Electronic Altimeter Receiver-Transmitter is the unit that both generates the pulses and handles reception, coordinating the timing and processing of the signals. The antenna simply radiates and receives the waves; it does not generate the pulses by itself. The height indicator is only a display of altitude, and the mission computer uses the data but does not produce the pulses. So the transmitter function lies within the Electronic Altimeter Receiver-Transmitter.
