Describe/Explain Radar operation? i.e. for example, how is radar used to detect an aeroplane? Show radar components and how they function to detect an aeroplane and how is the distance calculated https://www.explainthatstuff.com/radar.html
What is the equation to calculate the range to a target using Radar Systems. Use speed of light in the equation. https://www.radartutorial.eu/01.basics/Distance-determination.en.html
R = c * Tr/2 , c = speed of light, Tr = travel time back and forth
R in km = 0.15 * Tr (in micro sec) , speed of light = 150 meters in 1 microsecond
c = 3 * 10 to the power 8 m/s = 3 * 100 = 300 m/ micro sec = 0.3 km/ micro sec
What is the maximum unambiguous range? c * Tp/2 = c / (2 * freq)
Tp = Pulse repetition interval
Freq = 1/Tp or Tp = 1/f
What are the factors that influence the performance of Radars?
Does Antenna gain influence radar performance? if so why and how? May be explain with equations in addition to giving conceptual explanation
Does Antenna effective aperture influence radar performance? if so why and how? May be explain with equations in addition to giving conceptual explanation
Does Transmitter power influence radar performance? if so why and how? May be explain with equations in addition to giving conceptual explanation
Does System losses influence radar performance? if so why and how? May be explain with equations in addition to giving conceptual explanation
Does Radar cross section influence radar performance? if so, why and how? May be explain with equations in addition to giving conceptual explanation
What is the power density for Radars? Does it relate to receiver anyway? Can you give equations for power density for directive and isotropic antennas?
What is the uncommon parameter in the equation of power density for directive and isotropic antennas?
How do you calculate average transmitter power from Peak power?
Is average power a function of pulse width (tau), Tp – pulse-repetition period?
What is the power density of the echo signal?
