Patent ID: 7012738

Claim:
A Method of detecting and processing the amplitude and phase of signal waves, the method comprising: providing a modulated signal source SQ generating signal waves, which are modified on their path by a transmission medium or object or by reflection and scattering on at least one object; receiving by a receiving apparatus EM and there demodulating the received signal wave with a modulation signal 15 , which is related to the modulation of the signal wave; measuring and evaluating with respect to the amplitude of the modulated signal wave and the phase relationship of the modulation phase of the signal wave and of the modulation signal 15 , in which the incident signal wave is demodulated directly by a suitable mixing device (MIX), this mixing device distributing the signal wave energy or particles directly representing said wave energy particles, due to a conversion by an upstream converter (UMW), in a push-pull oscillation process with a wave energy oscillator or charge oscillator in the rhythm of and matched to a modulation signal onto at least two detection/readout outputs, as mixed products; feeding the respective output signals to a detection and readout unit (AUSL), these at least two output signals s a and s b being evaluated and further processed in a downstream evaluation unit (AUSW) with respect to the differential and the sum of these output signals; supplying a part of the signal source energy of the receiving apparatus directly as reference signals via a known channel; providing read out electrodes in at least two groups and including an associated or integrated shielding; and providing the groups of read out electrodes with a push-pull modulation voltage, the shielded electrodes supporting said charge oscillating process by means of appropriate static fields.
