Hello, i am trying to find a formula to calculate RSS because it has a different value each time.

Hello @ShiPu ,

Received signal strength is basically  signal strength of receiver and transmitter signal in power units such as dBm at the receiver site.  It is measured over a period of time and then averaged to generate RSS. Thus, for BGT60TR13C the normalized received antenna gain is considered with the measurement setup as shown below.

Both transmit and receive antennas are part of the measurement. For the measurement, the standard FMCW radar scheme is followed and the signal at all three receive antennas is recorded. Then the sensor is rotated into different angles and the measurement is repeated for each angle, resulting in an angle dependence of the received signal for all three receiver antennas and on the used center frequency of the chirp in particular direction, as described in this document: https://www.infineon.com/dgdl/Infineon-BGT60TR13C_Shield-ApplicationNotes-v02_02-EN.pdf?fileId=8ac78... 

Hope this helps!

Best regards,

Honey
