Abstract:

This final report discusses the technical results from four independent tasks. The effectiveness of the complex cepstrum technique to resolve multipathed acoustic signals was evaluated and compared to autocorrelation techniques. Significant improvements were made in a curvilinear ray theory propagation model, extending accuracy and improving certain algorithms. The maximum entropy spectrum analysis technique was evaluated in terms of estimation accuracy and parameter behavior. A brief description is given of software developed for the OASIS computer system.
