Abstract
Results are reported of comparative experimental studies between pulse-echo and correlation imaging systems. The latter is optimized by computer simulation to reduce the signal-to-clutter ratio. The experimental results in A mode show that in correlation experiments, the emitted power is about 10/sup 4/ times lower than the power needed in the classical pulse-echo technique to extract an echo signal from ambient noise.<>
