What is range resolution of a radar?
Range resolution is the ability of a radar to distinguish between two or more targets which are very close to each other. The degree of range resolution depends on: the width of the transmitted pulse. the type and size of the target. on the efficiency of the receiver.
What happens to the range resolution as bandwidth of the radar system increases *?
Radar using Intrapulse-Modulation
As a matter of course the receiver needs at least the same bandwidth to process the full spectrum of the echo signals. This allows very high-resolution (and a small radar range resolution cell) to be obtained with long pulses, thus with a higher average power.
What bandwidth does radar use?
Most radars, in practice, operate between 400 MHz to 36 GHz; however, there are some notable exceptions. The optical and radio portions of the electromagnetic spectrum occupy positions coincidental with two important transparent bands in the Earth's atmosphere and ionosphere.
Which factor determines the range resolution of a radar *?
Transmitter power and antenna size
The maximum range of a radar system depends in large part on the average power of its transmitter and the physical size of its antenna. (In technical terms, this is called the power-aperture product.)
