COMPARISON OF OPTIMAL AND QUASIOPTIMAL ALGORITHMS OF SIGNAL EXTRACTION IN ULTRASONIC THICKNESS MEASURING WITH THE PRESENCE OF STRUCTURAL NOISE
Conducted сomparisonof optimal and quasioptimal algorithms of spatiotemporal signal processing in ultrasonic thickness measurements with the presence of structural noise. It is shown that the optimal algorithm gives a little gain in relation to signal/noise ratio in comparison with quasioptimal algorithm. But implementation of optimal algorithm there are significant errors, which exceed the gain from application of optimal algorithm. It is concluded that, in practice, it is more appropriate to use quasioptimal algorithm of signal processing.
