What is Doppler FFT?

FFT Plot (Range-Doppler Plot): The FFT is used to convert radar time domain data to frequency domain. Detected objects and their Doppler signature are plotted in an FFT Plot. The x-axis represents the Doppler Frequency (which can be converted to Doppler Speed), and the y-axis is range.

How to plot range Doppler map in Matlab?

Use plotResponse to plot the range-Doppler response or step to obtain data representing the range-Doppler response. Include x in the syntax when you call plotResponse or step . If your data is not already dechirped, also include a reference signal in the syntax.

How can I improve the resolution of my Doppler?

Range resolution was obtained by using a short pulse and by frequency or phase modulating it in order to increase its frequency bandwidth. On the other hand, velocity (Doppler) resolution can be improved by increasing the time duration of the pulse.
