Posted under Cognitive Radio

Answer: (c).Burst Explanation:LORAN system sends a known burst signal with fixed periodicity from multiple transmitters. The receivers construct time difference of arrival hyperboloid curve to determine the location of the transmitter. LORAN provides published charts corresponding to hyperboloid curves, to find the intersection of two-time difference pairs.
