Hi,

I would like to know how the normalized antenna gain radiation pattern is plotted from the below link,

Rudresh,

Could you please elaborate on your request ? Is it on how the measurements were carried out to get the plot or something else?

Thanks and regards,

Hi Chetan,

Yes, you are correct I would like to know how those TX to RX patterns are plotted. In my case I have radiation patterns of individual TX and RX antennas.

Regards,

Rudresh

Hi Rudresh,

There is a correction needed in the TI resource explorer page, as the plot is measured numbers not simulated number.

These are measured results in an Anechoic chamber with the corner reflector placed around 3m. The sensor is mounted on the top of a rotator. FMCW chirp is transmitted with 3TX MIMO mode. At the receive side, the raw ADC data is saved for each rotation angle. FFT is applied to the raw ADC data, and the peak of the zero doppler signal around 3m is found and the complex values of each antenna of this peak range bin are recorded. These recorded values are used to generate this radiation pattern.

Thanks and regards,
