Convert bandwidth to range resolution
Assume you have a monostatic radar system that uses a rectangular waveform. Calculate the range resolution obtained using a bandwidth of 20 MHz.
bw = 20e6; rngres = bw2range(bw)
rngres = 7.4948
Calculate the range resolution of a two-way sonar system that uses a rectangular waveform. The signal bandwidth is 2 kHz. The speed of sound is 1520 m/s.
bw = 2e3; c = 1520.0; rngres = bw2range(bw,c)
rngres = 0.3800
bw— Signal bandwidth
Signal bandwidth, specified as any array of array of positive real values. Units are in hertz.
c— Signal propagation speed
Signal propagation speed, specified as a positive scalar. The
default value is the output of
Units are in meters per second.
This function assumes two-way propagation. For one-way propagation, you can find the required range resolution by multiplying the output of this function by 2.
The function computes range resolution from
