That's right. For the results in the paper, I used the whole data set of 2000 (training) + 250 (validation) + 250 (test) examples (= RD maps). The data set from the download is only a subset with 200 (training) + 25 (validation) + 25 (test) examples. The reason for this is its large size. The subset is sufficient for testing the pre-trained models and for demonstration purposes. If you are interested in the whole data set for more extensive testing and training, I could temporarily make it available for download. Note: Training data examples contain only the signal from one antenna, while validation and testing examples contain the signal from eight antennas (for validation measures concerning the angle of arrival).
Thank you so much. I want the whole data set for more research. Where can i download it ?
I treat the data set as 1024 samples 128 chirps 200 frames . I take out the first chirp of frame 3(contain 2 targets) and plot in time and frequency domain . data called "s_IF" and "s_IF_zero_interf_td" look the same . In fact , I want the data that include with interference and without interference . But i don't know the meaning of different data . So could you explain for this ? Thank you .
What you are looking for are the data contained in s_IF (with interference) and s_IF_clean (without interference). s_IF: IF signal from object reflections + AWGN + interference s_IF_clean: IF signal from object reflections
Also contained in the data: s_IF_clean_noise: signal from object reflections + AWGN s_IF_zero_interf_td: signal from object reflections + AWGN where all time domain samples that are affected by interference are set to zero. objects: contains the true ranges velocities and angles of the simulated point objects.
Note: The data is already in frequency domain (after the first FFT over the fast time samples within one ramp).
