Hello! This is from my IoT Connectivity class. Any help would be appreciated, thank you! 1.

(2 Point) RF Localization: Consider the case of a two antenna receiver. Recall that if the source is far away, the difference between the phases of the signals on the two antennas is related to the spatial angle of the source by: /2 = Dcos()/ where D is the separation between the two antennas, is the wavelength, is the difference between phase of signal received by the two antennas, and is the spatial direction of the source. Circle true or false. Explain your answer in no more than two lines.

(a) (True / False) To identify the location of the source, we need to measure the AoA from at least two receiver locations.

(b) (True / False) If D is multiple wavelengths, the system has zero noise, and the signal experiences no multipath, one can identify the direction of the source with very high accuracy from a single AoA measurement.
