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.

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.

What is Doppler ambiguity?

In pulse radar, the modulation of the carrier frequency is a periodic sequence of rectangular pulses. The frequency spectrum of the transmitted signal is a comb-shaped line spectrum. The line spacing of the spectrum is equal to the Pulse Repetition Frequency fPRF or PRF.
