a Experimental setup of dynamic interference environment. Tx1, Tx2, transmitters. Rx, receiver. MIMO, multiple-input and multiple-output. b Flow chart for demodulation of FMCW signal. c Spectrogram of demodulated FMCW signal for three tested conditions, calculated by Short-Time Fourier Transform on data sequences of 6.2 \({\rm{\mu }}{\rm{s}}\). d Signal-to-noise ratios for the three tested conditions. Trajectories of antenna Tx1 are plotted in grey colour
