This repository contains several scripts to save, read and parse raw data from DCA1000 EVM from Texas Instruments using compatible mmWave radar boards (60GHz and 77GHz) such as XWR12xx, XRW14xx, XWR16xx, xWR6843 and xWR1843.
The dca1000.py script is a modified version from the openradar library to automatically read configuration parameters from lua script file and convert radar data from two's complement to int16.
- Simply copy this folder wherever you prefer and copy lua script from
mmWave Studio Scriptsfolder toMMWAVE_STUDIO_INSTALLATION_PATH\mmWaveStudio\Scriptsand load it using mmWave Studio. - Edit
COM_PORTvariable in the lua script and assign it to the corresponding RS232 COM Port in your computer (XDS110 Class Application/User UART, the same mmWave Studio uses to connect to the board). When using this lua, no connection or reset is required as it is included in the script. - Modify mmWave Studio path in PARAMS parsing class through
CONFIG_FILEvariable if needed.
Modify emission and radar parameters in lua script and they will be automatically loaded in PARAMS class in Python.
By default, infinite measuring mode is used (number of frames set to 0). Three transmission antennas are configured and chirp emissions are in the order TX1 -> TX3 -> TX2. This can be changed in chirps configuration enabling or disabling TX antennas.
- Open mmWave Studio and load the lua script provided in this repository
- Run python data acquisition code!
An example script is provided to save data frames and the parameters used to configure the radar. Data is saved using pickle library.
An example of use is provided to instruct practitioners. A RadarData class is defined to transform byte data read from the device to radar data in two formats:
-- The property separated_vx_data contains the radar data reshaped as a NumPy array of shape (numChirpLoops, numVxAntennas, numADCSamples) where each chirp contains the following numVxAntennas arrays:
[ [TX1-RX1], [TX1-RX2], [TX1-RX3], [TX1-RX4], [TX3-RX1], [TX3-RX2], ... , [TX2-RX4] ]
Each [TXa-RXb] array is the signal emitted by TX antenna a received on RX antenna b with a total of numADCSamples samples.
-- The property separated_data contains the radar data reshaped as a NumPy array of shape (numTxAntennas, numRxAntennas, numChirpLoops, numADCSamples) to ease the access to specific TX-RX antenna pairs. Thus, all TX1-RX3 chirps can be accessed through separated_data[0,2].
