As a target is changing the angle from the view of a radar its velocity is observed as decreasing but its range is increasing and it follows sinusoidal(1+sinθ). Calculate the doppler phase shift of a varying range of a target that increase by a change in angle from 00 upto 900, for every 150 . If the initial range from the target is 100mt, and the frequency is 2GHz.Prepare a table of range and phase values for all of them in an order from 00 upto 900, with a change of 150. Then plot the graph between angle, Change in range and phase shift.
