A method and apparatus to segment-wise detect and bring into coincidence signal waveforms which can be converted into monotone and continuous trajectories, in particular for purposes of real-time pattern recognition, localization and monitoring optical and acoustic signals and to determine transit-time differentials. The desired monotone and continuous trajectories are made to coincide i n translation-invariant manner with the key signal waveforms which are also storable in reconfigurable manner. The said method and apparatus therefore detects in a very short time said trajectories with high accuracy of measurement. Even in other applications (Fig. 3), the determination of transit-time differentials implemented by the method of the invention takes the form of detecting key signal waveforms in the upper or lower signal detection unit C1a or C1b and in further processing the data in the subsequent multi-coincidence unit C2, shift-invariant parall el multi-template matching being carried out in the detection units C1a and C1b, wherein the trajectories are correlated in parallel and a set of transit-time differentials in the form o f an output vector D being emitted from the subsequent multi-coincidence unit C2. The method is suitable to accurately determine trajectories and accordingly is useful for instance to localize signal sources in space, to measure displacement trajectories, to measure speed and acceleration, etc.
