Patent ID: 7355924

Claim:
A sonar system, comprising: at least one sonar emitter; at least one sonar sensor configured to receive an echo from a signal generated by the at least one sonar emitter, wherein the at least one sonar sensor generates a raw data signal; at least one roll, tilt, and/or yaw sensor; processing means for transforming the raw data signal to an image data, wherein said image data has been rotated responsively to the sonar sensor's orientation as determined by the at least one roll, tilt, and/or yaw sensor; wherein said processing means generates a complete image with a single transmission; wherein the roll, tilt, and/or yaw orientation of said image data with respect to a fixed frame of reference and the successive display of multiple image data is orientated in the same fixed frame of reference; wherein the sonar sensor consists of multiple transducer elements and is configured in a Mills Cross orientation consisting of two orthogonal linear receivers; and wherein the sonar emitter consists of a broad beam transmitter.
