ECET 425 Week 1 Homework

1.A cable has the following parameters at 10 kHz:

Determine the characteristic impedance, attenuation constant (a), and phase constant (b) for this cable.

2.Derive the expression for the characteristic impedance of the symmetric T-section attenuator shown in the figure below. If R₁=50 Ω and R₂=100 Ω, find the characteristic impedance R_o.

What is the attenuation per section in decibels?

4.A section of a low-loss transmission line is 0.40 wave length long and is terminated in a short circuit. Its characteristic impedance is 73 ohms. The frequency of operation is 200 MHz. Determine the input impedance of the line section.

ECET 425 Week 5 Homework

1.A RADAR transmitter has a power of 20 kW and operates at a frequency of 10 GHz. Its signal reflects from a target 18 km away with a radar cross section of 12.5m². The gain of the antenna is 20dBi (G = 100 nominal gain). Calculate the received power.

2.A pulse sent from a radar returns 12 microseconds later to the radar. How far away is the target?

3.Police use Doppler shift radar to determine how fast a target is moving relative to the squad car. The Doppler shift equation is

4.If the police squad car is driving 55 mph and the perpetrator vehicle is driving at 65 mph in the lane in front of the squad car, what is the Doppler frequency shift?
