Time-Frequency Detection: Application to Sub-Bottom SONAR
© November 2000
Arescon Research has developed a method to detect narrow-band transient signals in a noise contaminated environment.
This method has some very desirable properties for applications where high accuracy and reliability is required for "time-of-flight" measurements. Very accurate ranging with a low "false alarm" rate and discarding of noisy signals is pre-requisite when signals are subject to further analysis.
This report demonstrates some of the properties of the time-frequency approach for post-processing of data from a sub-bottom profiling parametric sonar.
