upper plot: current frame lower plot: current frame - last frame you can see at the lower plot, first 100 sampler are particularly noisy. no large movement in the environment when running the radar. sensor : X4M03 radar development kit platform : ubuntu 16.04 with python3.5 I have tried modifying the radar configuration, such as dacmax, dacmin, pulse per step, iteration. and fps. but seems no big changes. the code to get the plot is attached(plot.py), modified from the sample code (pymoduleconnector/examples/XEP_X4M200_X4M300_plot_record_playback_radar_raw_data.py) remark: corresponding pymoduleconnector is needed to run the radar. pyqtgraph and numpy are needed as well. is it normal to have such signal from the radar?
