摘要

The speckle brightness adaptive algorithm has previously beennimplemented in approximately real-time on low frequency, one-dimensionalnarrays. To increase the speed of this technique, a temporally parallelnalgorithm and a spatially parallel algorithm are described. Theoreticalnanalyses, simulation results and experimental measurements are presentednfor these algorithms. Theoretical predictions indicate that thesentechniques increase the correction speed, but some decrease in thenaccuracy of the compensating phase estimate occurs. Simulation resultsnindicate that these parallel algorithms perform well at removing theneffects of phase aberration. Preliminary experimental measurementsndemonstrate the correction speed improvements achievable with thesenalgorithms
