IWR1443: read range profile

HS FAE Germany
Mastermind 32250 points
Part Number: IWR1443

Hello,
customer wants to read out the range profile of all 4 receivers. In the firmware you can only read out the range profile of the first antenna.

    Hi Holger,

    I'm not sure if I completely understood your question, but by firmware, do you mean the .bin file for the Power Optimization for IWR1443 77GHz-Level Transmitter Reference Design? If so, this reference design is aimed at highlighting strategies for reducing power consumption for low power applications (4 to 20 mA) and hence the configuration programmed in this design enables only one receiver. There is no such restriction at the device or SDK level. In fact, the IWR1443 mmWave SDK Demo uses data from multiple receivers for Angle of Arrival computation. You can use the mmWave Demo Visualizer with the IWR1443 mmWave SDK Demo to understand how it uses the RX data from multiple receivers to generate the 3D plot. Details of the processing and output data structures are available in the doxygen documentation provided with the IWR1443 mmWave SDK demo. Please refer to C:\ti\mmwave_sdk_01_00_00_05\packages\ti\demo\xwr14xx\mmw\docs\doxygen\html\index.html

    yes, this .bin file. But the demo delivers only complete processed data. Customer wants to read/visualize each antenna to get better understanding on the angle dependancy of each antenna. They want to limit the receiver angle for target eg 5°, 10°, 15° angle window to get a feeling of the sensitivity. Therefore they want to get the FFT data / range profile of each antenna element.

    Hello Holger,
    If you want to get the raw ADC data out you need to use the capture demo application which sends the raw data out over the LVDS or CSI interface. You will need a LVDS or CSI receiver on the other side to capture this data and interpret it.
    Note that the present capture demo only sends out data for one of the receiver channels at a time, but it can be modified to send out the data from all the 4 RX channels.
