Measurement of the power value

[miaozhang97bosch]

Hello, thanks for sharing your work. I wonder which mathematical unit is used in the power value measurement.
I saw that the value is normed by 1e+13:

cube_norm = (cube_norm)/1e+13,
I check the value after that is normally in the scale of 1.5e-2, if we switch it back and then put it in the RCS dBsm scale, it will be something like 10log(1.5e+11) =100+dBsm. That kind of large RCS value is not so realistic for target like sedan or bus.

If it is simply the receive power measurement, is it feasible to convert that into RCS value by radar equation (Gain, transmit power...)?
I'd appreciate it if you could give me some hints about it. Looking forward to your reply. Thanks!
