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 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 is the meaning of the colors in the radar ghosts?
The colors are basically the signal, or kind of like how much energy the ghost has. Red is a strong signal, followed in order by yellow, green then blue.
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.
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.
Why is reflection of signal useful?
Reflection of a transmitted signal is the basic premise of radar and sonar.
What is considered as nature's radar?
pegeon
Does radar detectors beep?
Most will beep when they receive a signal.
What is considered nature's radar?
Nature's radar is echo location. Dolphins and whales use it to communicate underwater and bats use it to find the location of their prey.
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.
What do transponders on aircrafts do?
They do a few different things these days but their primary role is that of radar. The use of radar that flies from a station, hits the aircraft and bounces back to the station is very limited. In most normal situations the ground station sends out a signal. The transponder receives the signal and transmits the return signal. It allows for greater range of the radar and also allows extra info to be passed to the radar controller like height and aircraft ID. This is known as Secondary Radar.
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 much time would elapse between sending of a radar signal to the moon and the return of the signal?
about 2.56 seconds
Where is mirror b?
you'll get a signal from your radar and when you use it it'll tell you where he is
