The LC circuit of a radar transmitter oscillates at 38.9 GHz. (a) What inductance is required for the circuit to resonate at this frequency if its capacitance is 3.80 pF? pH (b) What is the inductive reactance of the circuit at this frequency? ?
A radar gun operates at a frequency of 10.5 GHz. A beat frequency of 2.46 GHz is then observed by the radar gun when it is used on a car heading towards the radar. a) Assume a temperature of 20 degrees Celsius, calculate the velocity of the car that is driving towards the officer. Give your answer in m/s and then convert to mph. b) Assuming a temperature of 0 degrees Celsius, find velocity in terms of m/s and then...

A monostatic radar operates at 4 GHz and has a directive gain of 30
dB. The radar is used to track a target 10 km away and the radar
cross section of the target is 12 m^2. If the antenna of the radar
transmits 80 kW, calculate the power intercepted by the target.

How deep does a radar wave at 2 GHz travel in seawater before its amplitude is reduced to 10^-5 of its amplitude just below the surface? Assume that μ=μ0. ε=ε0, σ=4 S/m.
6) A 2 GHz ground-penetrating radar sends a signal into non-magnetic semi-dry soil that has 2.5 relative permittivity and 10-2 loss tangent. Find the distance the signal travels before: (a) its electric field amplitude is reduced by 20%, (b) its phase shifts by 180°, and (c) its average power density is reduced by 10%.
A police radar gun operates at an emitted frequency of 10 GHz (10 x 109 Hz). The police officer aims his radar toward a speeding car moving directly away from him at v = 0.2c. The signal reflects off the car and travels back to the police officer where he detects it. What frequency does he detect? Instead the police officer aims the radar at an airplane flying directly overhead at an altitude of 10,000 m with v=0.2c in a...
Outline the principles of operation of a radar altimeter, including an explanation of the factor that control its horizontal and vertical spatial resolution.
The word radar is an abbreviation for Radio Detection and Ranging. Radar is used in many applications such as air traffic control, aircraft navigation, law enforcement and remote sensing. In this project you will investigate the different types of radars available and determine the best one to use in a speed gun application. Pulse Radar Draw a block diagram of a monostatic (same antenna is used to transmit and receive) pulse radar system and explain the role of each component....
Q: (a) The antenna of a 38 cm radius dish used as a satellite receiver in the Ka-band is 25.5 GHz - It operates in the 31.5 GHz frequency band. Find out where the far-field region begins for this antenna. (b) A radar operating in monostatic configuration broadcasts at 10KW power and the receiving power of this radar sensitivity is 12 pW. The gain of the radar antenna at 12 GHz in the maximum radiation direction is 16 dB. This...
