1.	In which of the following scanning the phase of the radiator is constant at one frequency?(a) Phase scanning(b) Frequency scanning(c) Both Phase and frequency scanning(d) Neither Frequency nor Phase scanningThe question was posed to me at a job interview.I would like to ask this question from Phased Array topic in section Phased, Adaptive and Binomial Arrays of Antennas
Answer» Correct ANSWER is (b) Frequency SCANNING The best explanation: In frequency scanning, for one frequency all radiators will be in PHASE. As the frequency is CHANGED then a corresponding phase shift occurs and the beam is scanned. In phase scanning the phase shifters are used and radiators have different phases.
