Multimission And Multispectral Sonar
Patent No. EP3362817 (titled "Multimission And Multispectral Sonar") was filed by Rsonic on Apr 2, 2017. The application was issued on Nov 27, 2024.
Patent Summary
A survey system for water-going vehicles comprises a multibeam echo sounder featuring a sonar acoustic transceiver and a Mills cross configuration, where a single projector array and a single hydrophone array are arranged orthogonally to form beam intersections. The transceiver synthesizes a single transmitter message incorporating signals from $N$ non-overlapping frequency bands, each supporting a distinct mission. This message ensonifies an elongated rectangular swath of a waterbody bottom. To enable recognition of frequency-dependent characteristics of scattering centers, at least two frequency bands are widely spaced. Such spacing may be defined by center frequency separation of at least twice the narrowest signal bandwidth, at least 30% of the lower center frequency, or by statistically significant differences in backscatter strength.
