What curve is obtained by plotting the time difference of arrival?(a)

1.	What curve is obtained by plotting the time difference of arrival?(a) Parabola(b) Sphere(c) Hyperbola(d) EllipseI have been asked this question in an interview for internship.This key question is from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio
Answer» Correct choice is (C) Hyperbola The EXPLANATION: The time difference of arrival approach involves computing the time difference between the reception of a signal at one LOCATION and the reception of the same signal at a DIFFERENT location. The plot of time difference of arrival produces a hyperboloid surface with its foci at the two receivers.
