Convert range resolution to required bandwidth
bw = range2bw(r)
bw = range2bw(r,c)
Assume you have a monostatic radar system that uses a rectangular waveform. Calculate the required pulse width of the waveform so that the system can achieve a range resolution of 10 m.
r = 10; tau = 1/range2bw(r);
r— Target range resolutionarray of positive numbers
Target range resolution in meters, specified as an array of positive numbers.
c— Signal propagation speedspeed of light (default) | positive scalar
Signal propagation speed, specified as a positive scalar in meters per second.
