- Generate the transmitted and received signals for FMCW radar, considering the carrier frequency, sweep bandwidth, sweep time, and target range and velocity.
- Perform a “dechirp” operation on the received signal using the transmitted signal as a reference. This will produce a beat signal that contains the range and doppler information of the target.
- Perform a fast Fourier transform (“fft”) on the beat signal along the fast time dimension to obtain the range spectrum.
- Perform another FFT on the range spectrum along the slow time dimension to obtain the doppler spectrum.
- Plot the magnitude of the doppler spectrum in decibels as a function of range and doppler frequency or radial speed.
