Abstract : A new coherent fluctuation based processor, designed AWSUM III(434), is described and results are presented. The processor is a combination of the Wagstaff's Integration Silencing Processor (WISPR) III (WISPR III) and the Advanced WISPR Summation (AWSUM) processor. While WISPR III achieves signal-to-noise ratio (SNR) gains of about 14 dB, AWSUM III(434) achieves gains of about 24 dB. In addition, the spatial resolution of AWSUM III(434) is significantly increased and the submerged source identification capability is measurably enhanced, e.g., 10 dB.
