The ref. unit mentioned is perfectly fine. Some microphone manufacturers use 1 dyne/cm^2. This would translate into -74 dB instead of -94 dB because the reference pressure applied is 0.1 Pa. So you can do the same math, just subtract -20 dB. To resume: to calculate the sensitivity you must: 20.*log10(sens.)-20. In you case, this would imply a sensitivity (...

Are there any resources where I can study about the algorithms it uses to calculate the direction? "positioning" and direction finding are typically two different things; you can use direction finding with enough observers for positioning, but it's not the only way, and probably not used here. UWB and angular resolution is hard, because the usual &...

Amplitude modulation is a linear operation (excluding the carrier in the classical AM) and does not introduce harmonics due to the modulated signal. Sidebands are not harmonics. They are created as the message signal spectrum is shifted up to carrier frequency. Frequency mixing of a message signal with a sinusoidal carrier, another definition of AM, does not ...
