Impact of unequal distances among acoustic sensors on cross-correlation based fisheries stock assessment technique
Abstract Cross-correlation based fisheries stock assessment technique utilized array of multiple acoustic sensors which were equidistant pair. However, at practical implementation of this technique, equal distances among acoustic sensors is sometimes challenging due to different practical phenomenon...
