Range Doppler coupling
dr = rdcoupling(fd,slope)
dr = rdcoupling(fd,slope,c)
Calculate the true range of the target for an FMCW waveform that sweeps a band of 3 MHz in 2 ms. The dechirped target return has a beat frequency of 1 kHz. The processing of the target return also indicates a Doppler shift of 100 Hz.
slope = 30e6/2e-3; fb = 1e3; fd = 100; r = beat2range(fb,slope) - rdcoupling(fd,slope);
fd— Doppler shiftarray of real numbers
Doppler shift, specified as an array of real numbers.
slope— Slope of linear frequency modulationnonzero scalar
Slope of linear frequency modulation, specified as a nonzero scalar in hertz per second.
c— Signal propagation speedspeed of light (default) | positive scalar
Signal propagation speed, specified as a positive scalar in meters per second.
