摘要： 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.
摘要翻译： 在检测环境中对信号进行同步解调的系统和过程，以便通过脉冲信号方法改善频率，幅度和/或相位响应。 根据优选实施例，返回信号在对应于其相应的发送信号已经中断或已经下降到一定水平的时间被解调。 可以使用多个传输频率，发射机和/或传感器等。
