ABSTRACT:
Systems and processes for synchronous demodulation of signals in detection contexts in order to improve frequency, magnitude and/or phase response over pulsed signal methods. According to a preferred embodiment, a return signal is demodulated for the time corresponding to when its corresponding transmitting signal has been discontinued or has fallen below a certain level. Multiple transmission frequencies, transmitters, and or sensors, among other things, may be used.
