Dynamic wide-bandwidth acoustic form-function determination
The use of near-real-time digital signal processing to obtain acoustic data on the scattered form function of an object is considered. Modifications inherent in the analog to digital conversion process are found not to alter the analog data representation. The experimentally obtained backscattered f...

| Zusammenfassung: | The use of near-real-time digital signal processing to obtain acoustic data on the scattered form function of an object is considered. Modifications inherent in the analog to digital conversion process are found not to alter the analog data representation. The experimentally obtained backscattered form function for an ’’effective’’ infinite aluminum cylinder is presented for the region 4?ka?21. |
