This report summarizes an effort carried out at the Naval Surface Warfare Center Panama City NSWCPC under SERDP funding to develop a performance prediction capability for sonar against UXO. This development built upon existing sonar performance prediction software PCSWAT developed to aid sonar design for underwater mine-countermeasure purposes at NSWCPC. The wide variety and distribution of UXO required a number of scientific issues to be resolved in order to update PCSWAT appropriately. UXO are expected to be completely buried, sometimes quite deeply. Thus, the sonar response of buried targets needed to be investigated and new target scattering algorithms used to account for burial effects formulated, checked through controlled measurements, and incorporated into PCSWAT. Among the issues that were explored to accomplish this are what environmental parameters are most important in modeling the response of buried targets, how do we accurately measure these inputs, can the target models currently built into PCSWAT be extended to the shapes and sizes encountered with UXO, and what environmental factors affect acoustic detection of buried targets the most. Both modeling and experimental measurements were carried out to answer these questions to the degree possible and these and their results will be discussed in this report.
