⋯∙Predict/Calculate A highway patrolman sends a 28.250- GHz radar beam toward a speeding car. The reflected wave is lower in frequency by 2.97 kHz . (a) Is the car moving toward or away from the radar gun? Explain. (b) What is the speed of the car? [Hint: For small values of x, the following approximation may be used: (1 x)^2 ≈1 2 x . ] | Numerade

SOLVED:Millimeter-wave radar generates a narrower beam than conventional microwave radar, making it less vulnerable to antiradar missiles. (a) Calculate the angular width of the central maximum, from first minimum to first minimum, produced by a 220 GHz radar beam emitted by a 55.0 -cm-diameter circular antenna. (The frequency is chosen to coincide with a lowabsorption atmospheric "window.") (b) Calculate the same quantity for the ship's radar described in Problem 20 .

A radar for tracking aircraft broadcasts a 12 GHz microwave beam from a 2.0 -m-diameter circular radar antenna. From a wave perspective, the antenna is a circular aperture through which the microwaves diffract. What is the diameter of the radar beam at a distance of 30 km ? b. If the antenna emits 100 kW of power, what is the average microwave intensity at 30 km ? | Numerade
