DCA1000EVM: Getting the angular plot from raw data from DCA

Hello Alex,

Can you be more specific with what you are looking for? By angle plot do you mean angle estimation? What you have circled from the visualizer screenshot is simply the point cloud. Is there a reason you want to use raw data for this? You would need rangeFFT and Doppler FFT to calculate range-doppler heatmap, then CFAR is used for detection, and then angle estimation after the third FFT which is applied for every detected point.

Thanks for the response. Let me clarify this, we need to obtain the PDP for each angle using the phase differences between the array receptors. But we actually have the PDP for each receptor.

Is there any simpliest way to get the data from the DCA apart from getting the raw data?

Best Regards,

Alex

Hello Alex,

It seems you are just trying to get point cloud data which has that angle estimation. You can check all that data output that comes from the sensor via UART on our UART Data Output guide on the Radar Toolbox. This is by far the simplest method of getting sensor data. Does the list below contain the information you are looking for from the sensor?

The DCA1000 is for getting the unprocessed, unfiltered, raw IF signal straight from the ADC to run your own algorithmic processing on for DSP/radar experts.
