    • A beat-product radio imaging method (RIM) system uses a matched continuous wave (CW) transmitter and receiver to electronically image material in between. Signal attenuation measurements are taken from a number of different transmitter and receiver perspectives around the material. The transmitter and receiver each have a crystal oscillator rated at 10-ppm or better frequency uncertainty. The receiver's crystal oscillator is used as a local oscillator to beat down the transmitter's carrier frequency to baseband. The frequency error between the local oscillator and the transmitter carrier frequencies produces a beat product of less than one Hertz in frequency and its magnitude is inversely proportional to the path attenuation between the transmitter and receiver. An extremely low-pass filter is used to remove everything above one Hertz in the detector. The receiver sensitivity is therefore extraordinarily high.
    • 节拍产品无线电成像方法(RIM)系统使用匹配的连续波(CW)发射机和接收机对其间的材料进行电子成像。 信号衰减测量取自材料周围的许多不同的发射器和接收器透视图。 发射器和接收器各自具有额定为10 ppm或更高频率不确定度的晶体振荡器。 接收机的晶体振荡器用作本地振荡器,以将发射机的载波频率降低到基带。 本地振荡器和发射机载波频率之间的频率误差产生频率小于1赫兹的拍频,其幅度与发射机和接收机之间的路径衰减成反比。 一个极低通滤波器用于去除检测器中高于1赫兹的物体。 因此,接收机灵敏度非常高。

    • An unsynchronized acoustic or radio-frequency (RF) computed tomography (CT) imaging system with matched, but independent, continuous wave (CW) transmitters and receivers configured to radiate acoustic or RF transmissions in a plurality of vector paths through solid geologic material. A computer calculates and displays tomographic images constructed from individual acoustic or RF path signal travel time or attenuation measurements logged from registered locations from the CW transmitters and receivers after their being shuttled amongst a number of different transmitter and receiver perspectives available around said geologic material to generate data necessary for computed tomography. Each of the transmitters and receivers include independent unsynchronized crystal oscillators rated at 10-ppm or better frequency uncertainty to produce and to detect CW radio frequency (RF) transmissions.
