摘要：In order to determine movements of two subjects, two or more signals ofdifferent phase are obtained which depend on the movement, and processed by locatingconstellation status of the signals in at least one co-ordinate axis system, it must have at

least six separate segments rotationally displaced. Where there are two or more co-ordinate axis systems, each must have an axis radiating from an origin. The change in theconstellation states is monitored using at least two processed data samples obtained bysampling the signals at a suitable clock rate. It is possible to derive a prediction of valuesof the signal and filter the signals in dependence on the prediction. The second co-ordinate axis system may be rotatable relative to the first co-ordinate axis systemenabling the provision of a movable region of uncertainty.
