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.
Intensity is a measure of incoming power per unit area. If I is the intensity of the incoming energy within an illuminated region of area, A, then the total received power is given by: P = JA where I depends on the power of the radiating source, how it spreads and how far away it is from the illuminated region. lashlight on a Wall Suppose that a flashlight beam spreads uniformly over a circular region as shown in the figure above.

Need Help? Submit Answer ARHSCALC1 5.2.062. Read It MY NOTES With the installation of noise suppression materials, the noise level in an auditorium was reduced from 95 to 81 decibels. The level of sound 3 (in decibels) with an intensity of I is B(I) = 10 log10 (I/I0), where Io is an intensity of 10-16 watt per square centimeter, corresponding roughly to the faintest sound that can be heard. Use this information to find the percent decrease in the intensity level of the noise as a result of the installation of these materials.
