Abstract :
Split-spectrum signal processing has been shown to be effective for the case in which the signal and noise are highly correlated, a situation that is common in nondestructive testing. This paper combines frequency diversity with space diversity through a two dimensional realization of split spectrum processing. Split-spectrum design procedures, software and test results are provided
