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 pulse compression technique?
Pulse compression is a signal processing technique commonly used by radar, sonar and echography to increase the range resolution as well as the signal to noise ratio. This is achieved by modulating the transmitted pulse and then correlating the received signal with the transmitted pulse.
How do pulse compression and wide bandwidth benefit the radar system performance?
Pulse compression allows a radar to utilize a long pulse to achieve a large radiated energy, but with the range resolution of a short pulse of wide bandwidth. It achieves this by modulating the long pulse of width T to obtain a bandwidth B >> 1/T.
What is pulse width range?
Two pulse widths are available for transmission. These widths are 1.57 µS and 4.5 µS.
