Abstract:

This work investigates the viability of Gold code phase modulation in acoustic tomography, a technique for large scale measurement of ocean characteristics. Maximal-length sequences are currently used for modulation, requiring time division multiplexing of tomographic signals to avoid interference. The proposed alternative scheme of code division multiplexing Gold code modulated signals promises more rapid, simultaneous ocean projections. Computer simulation enables side-by-side comparison of the Gold code and maximal-length sequence modulating methods. Based on favorable results, a specific set of Gold codes is recommended for future use in a tomography experiments. Theses. RH
