What is the relation between bandwidth and pulse width?
width is the duty cycle of a pulse in time domain, which is inversely proportional to the pulse bandwidth in frequency domain. The pulse width of a Gaussian pulse is defined as the pulse's temporal width at half of the maximum amplitude.
What is radar bandwidth?
Bandwidth B, BW or Δf is the difference between the upper and lower cut-off frequencies of radar receiver, and is typically measured in hertz. In case of a baseband channel or video signal, the bandwidth is equal to its upper cut-off frequency.
What is the bandwidth of a radar pulse?
The main frequency bands used by weather radar are the S-band (3 GHz), C-band (5 GHz), and X-band (9 GHz).
Why bandwidth is inverse of pulse width?
For example, if the width is reduced by 2, it's bandwidth increases by two. Whether it is the baseband or passband, this higher bandwidth is reflected when the pulse width is decreased. This simply follows from the inverse relationship between time and frequency for a given signal.
