IWRL6432BOOST: RDIF interface | Real value of the signal

Part Number: IWRL6432BOOST
Other Parts Discussed in Thread: IWRL6432

Regarding the RDIF interface for capturing raw ADC data, there are no reference/documentation of the data format of the binary file generated using DCA1000 and mmWave Studio 3G, only a example script of decoding the data in Matlab is provided which is not much helpful to understand RDIF interface.

Regarding the captured data, is the captured data real-part of the signal or absolute value of the signal?

Is it possible and how to get the phase information from the raw ADC data?

Hi,

The IWRL6432 has real-only RX channels:

Can I get any references to RDIF interface provided for raw ADC capture? I don't find any on ti.com or searching the web either. Yeah, I understand it has real-only rx channels, my question is that, is it the magnitude of the complex signal or only the real part of the complex signal, to put it succinctly, is it |a + bj |, or only the value of a in (a + bj)

Hi,

It should be the real portion (the value of a in a + jb)

Thank you for the reply. Is the signal we are getting is IF (Intermediate Frequency) or I (In-phase)? Can I get any references to understand the RDIF (Radar Data Interface)?
