What is echo signal in radar?
\n"Noun. 1. radar echo – an electronic signal that has been reflected back to the radar antenna; contains information about the location and distance of the reflecting object. electronic signal – a signal generated by electronic means. Radar echo – definition of radar echo by The Free Dictionary" https:\/\/www.thefreedictionary.com<\/a> \u203a radar+echo<\/p>\n

How does power density of the echo signal differ from the received power by the radar? Conceptually and in the equations?
\nAns: Ae = effective area of the receiving antenna<\/p>\n

What is the relation between G (Gain in the direction of target) and Ae? Any explanation of the equation and relation?<\/p>\n

What are the units of the parameters in the equations?<\/p>\n

What is the symbol used for Wavelength?<\/p>\n

How do you calculate the distance beyond what the target cannot be detected? i.e. Rmax, give the equation and explain<\/p>\n

How can you achieve a long distance?<\/p>\n

To get a long distance, will Pt need to be large?<\/p>\n

To get a long distance, will radiated energy need to be concentrated into a narrow beam?<\/p>\n

To get a long distance, will the received energy must be collected with a large antenna?<\/p>\n

To get a long distance, will the receiver must be sensitive to weak signals?<\/p>\n

Is the predicted radar range very accurate or usually optimistic? why or why not?<\/p>\n

What are the parameters that can make the predicted radar range not very accurate?<\/p>\n

Can you describe the maximum range of a Radar just by one number?<\/p>\n

Is it true? radar range (max) must include probability, the target type, and range possible<\/p>\n

What are the unpredictable or statistical parameters in the equation for max range?<\/p>\n

Is Smin = minimum detectable signal predictable in the equation?<\/p>\n

Is target cross section (sigma) predictable in the equation?<\/p>\n

Are meteorological conditions predictable in the equation?<\/p>\n

What do you mean by Smin = minimum detectable signal ? Any little details in any direction?<\/p>\n

Is Smin = minimum detectable signal: affected by noise energy?<\/p>\n

Does Smin = minimum detectable signal: also depend on the threshold set at the output of the receiver? Why is the threshold there? What happens if you lower the threshold? Does low threshold mean less perfection?<\/p>\n

Where does noise in the receiver originate from? Can the receiver itself introduce noise? What can be different sources of noise?<\/p>\n

What is thermal noise power? Give the equation. Explain the concept and the equation. k* T * Bn, T in kelvin<\/p>\n

Half-power bandwidth? Noise bandwidth? 3-DB bandwidth : what are these? What is the relation with Bn or thermal noise power if any?<\/p>\n

What are the different sources of noise?
\nGalactic, Solar, Atmosphere, man made, Ground, Receiver<\/p>\n

True or false? Noise entering the filter is Gaussian<\/p>\n

How does Rayleigh relates to the probability density of a narrowband IF filter?<\/p>\n

Probability of false alarm: what is the equation? What is the relation with TNR (Thermal noise ratio) and Bandwidth? Give a diagram.
