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 bandwidth in MHz of the waveform so that the system can achieve a range resolution of 10 m.
rngres = 10; c = physconst('LightSpeed'); bw = range2bw(rngres,c); bwMhz = bw/1e6
bwMhz = 14.9896
The required bandwidth is approximately 15 MHz.
Now, find the required pulse duration in microseconds.
tau = 1/bw*1e6
tau = 0.0667
r— Target range resolution
Target range resolution in meters, specified as an array of positive numbers.
c— Signal propagation speed
Signal propagation speed, specified as a positive scalar in meters per second.
This function assumes two-way propagation. For one-way propagation, you can find the required bandwidth by multiplying the output of this function by 2.
The function computes
