1.	Which of the following is false with respect to primary radar?(a) Friend or foe identification is possible(b) Height of the aircraft cannot be determined(c) Has a wide range(d) Requires high powerThe question was asked in an interview for internship.The question is from Primary and Secondary Radar topic in portion Surveillance Systems, Mapping and Multimode Radars of Avionics
Answer» The correct answer is (a) Friend or foe identification is possible For explanation: Friend or foe identification is not possible in primary radar and hence it is hard to determine if the aircraft is an enemy or friend. It has a WIDE RANGE and REQUIRES HIGH transmitting power due to the TWO way travel of the radar signal.
