Question

Which of the following is true with respect with solid state transmitters in pulsed radar altimeters?

(a) Input power is around 100W

(b) Use receiver pre-amplifiers

(c) High reliability

(d) Small size

This question was addressed to me in a job interview.

The doubt is from Radar Altimeter topic in chapter Celestial Navigation, Doppler and Altimeter Radars of Avionics

Answer 1

Correct answer is (a) Input power is around 100W

For explanation: The early pulsed radars were evolved to 5W solid state transmitters incorporating receiver pre-amplifiers. They also provided a high degree of reliability, low probability of intercept, small size, and high accuracy.
