The time for a radar signal to travel to the moon and back a one way distance of about 3.8108 IS?

Electromagnetic waves travel in free space at about a rate of 3.0 x 10^8 meters per second. A one way trip to the moon is about 3.8 x 10^8 meters so there and back is about 7.6 x 10^8 meters.
Then just divide the total distance by the rate.
(7.6 x 10^8) / (3.0 x 10^8) = 2.53 seconds

round-trip to the moon and back is about 2.54 seconds.

What is minimum detectable signal in a radar system?
the minimum discernible signal is the ability of the radar to detect the smallest return echo,this feature requires performing test according to situation display data
How does a Doppler radar determine the direction a storm is moving?
The Doppler part only detects motion towards and/or away from the radar antenna. To find a direction of travel (on any radar) you must watch the object (such as a storm) over time and watch it move. To find motion by doppler the radar must detect the frequency difference of the return signal - there will be a (very) small increase if the object is moving closer (and lower if moving away).
How long does it take a radar signal to go and return to the originating radar unit from an airplane that is 275 mi away?
2.953 milliseconds = 0.002953 second (rounded)
How does the frequency of a car's returning radar signal chang if the car moves away from the you radar source?
It's frequency reduces as the car gets further away.
What does the Doppler radar measure?
A narrow microwave signal is directed at the moving vehicle at a known frequency, due to its motion the reflected signal will arrive back at the radar at a different frequency, an algorithm in the radar processor converts this difference to give the vehicles speed. Presumably the angle between the cop and the speeder will have to be taken into account as well.
What does radar measures?
It measures the time it takes for a radio signal of a particular frequency to travel to a target and back. It also measures the strength of the signal when it returns. Based on the travel time of the signal, the radar can measure the distance of the target. Once the radar receives the 2nd signal, it can calculate the velocity of the target. The strength of the signal can be used to determine the size of the target.
How a radar operates as a distance finder?
It measures the time for the reflected signal to return. Early RADAR sets made this measurement and directly converted it to distance by using a CRT with calibrated markings on its face in units of distance. Modern RADAR sets use high speed digital counters then compute and show the distance numerically.
What is the main advantages of Doppler radar over conventional weather radar?
Conventional radar works by transmitting short pulses of electromagnetic energy. A small fraction of the waves that are sent out is scattered by a storm and returned to the radar, the strength of the returning signal indicates rainfall intensity and the time difference between the transmission and return of the signal indicates the distance of the storm. Doppler radar not only performs the same tasks as convention radar but also has the ability to detect motion patterns associated with tornadoes and severe thunderstorms, the conventional radar cannot.
How does the frequency of a cars returning radar signal change if the car moves away from the radar source?
The frequency of the radar signal does not change. Be it a cop getting you speed, or a modern car with Brake assist (they use a radar signal to assist keeping a safe distance) it's all timing, how long from the radar source to return to source. If a police car is still, and you are moving away, the increase in return of signal time tells the computer in the officer's car your speed. Even if you are going toward each other, the computer knows the speed of the officer's car and again, signal return time factored in with speed of cop car the computer can give an instant, real-time speed.
What is a reflected radar signal called?
Returns.
What is radar duplexer?
duplexer is the device that can separated the trasmitted signal and received signal.
Why is reflection of signal useful?
Reflection of a transmitted signal is the basic premise of radar and sonar.
Does radar detectors beep?
Most will beep when they receive a signal.
What does dopler radar do?
A Doppler radar is a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object's motion. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, meteorology, police speed guns,[1], radiology, and bistatic radar (surface to air missile).
What is the distance of a radar detector?
Depends, Radar detectors like the V1 have a distance of about 3 miles with constant on radar on straight aways. You have to take in account curves, hills, and other factors.
How can you calculate speed of radar?
Radar emissions are electromagnetic radiation that travel at the speed of light.
Do they make a detector that locates police?
There is a device called a radar detector, but it will only detect a radar signal, not police in general.
