Millimeter-wave Capture Standard (mmwave-capture-std)

mmwave-capture-std is a fast, reliable, and replicable Texas Instruments millimeter-wave capture toolkit, focus on data capturing and raw data parsing.

It stands out with three key attributes:

1. Fast: It parses raw data into np.ndarray[np.complex64] 2.09 times faster than state-of-the-art packages (0.59s v.s. 1.239s).

2. Reliable: It makes users easily identify and debug hardware issues, and provides fine-grained control over different hardware. It achieves this by comprehensive logging (stderr & file) and by separating the hardware setup from the data capture code.

3. Replicable: It simplifies the process of replicating the recording setup by using a toml config file to manage capture hardware, layout the dataset as HDF5-like structure, and provide sensor config files to each capture result.

Capture Millimeter-wave Raw Data is Easy

Here is an example of using mmwave-capture-std to capture mmwave data from IWR1483BOOST and DCA1000EVM:

bash $ uv run mmwavecapture-std examples/capture_iwr1843.toml 2023-06-02 :43.91 | INFO | ...:...:225 - Capture ID: 0 2023-06-02 :43.91 | INFO | ...:init_hw:230 - Initializing capture hardware `iwr1843`.. 2023-06-02 :49.32 | SUCCESS | ...:init_hw:245 - Capture hardware `iwr1843` initialized 2023-06-02 :49.32 | SUCCESS | ...:init_hw:247 - Total of 1 capture hardware initialized 2023-06-02 :49.32 | INFO | ...:capture:258 - Adding capture hardware `iwr1843` 2023-06-02 :49.32 | INFO | ...:capture:121 - Preparing capture hardware 2023-06-02 :49.32 | INFO | ...:capture:125 - Starting capture hardware 2023-06-02 :49.42 | SUCCESS | ...:capture:128 - Capture started 2023-06-02 :52.49 | INFO | ...:capture:132 - Capture finished 2023-06-02 :52.49 | INFO | ...:capture:134 - Dumping capture hardware configurations 2023-06-02 :52.49 | SUCCESS | ...:capture:270 - Capture finished, all files ...

Nice and easy! Your capture result will be stored like this with HDF5-like structure:

bash ☁ mmwave-capture-std [main] tree example_dataset example_dataset └── capture_00000 ├── capture.log ├── config.toml └── iwr1843 ├── dca.json ├── dca.pcap └── radar.cfg

You probably will need to modify the configuration to reflect your capture hardware setup. Change the following setting in example/capture_iwr1843.toml to your setup: (assume you did not change any setting on DCA1000EVM EEPROM)

toml [hardware.iwr1843] dca_eth_interface = "enp5s0" radar_config_port = "/dev/ttyACM0" radar_data_port = "/dev/ttyACM1" capture_frames = 10
