摘要： A winch is employed for deploying a probe to a precise depth within a water column for making and recording physical measurement within such water column. More particularly, the winch rapidly unspools a line from an underway vessel, while maintaining minimal but constant line tension, as a probe, tethered to such line, descends within the water column in a "near" free-fall to a predetermined depth and then stops. The line lacks means for communicating its depth to the winch. The probe achieves a predictable descent behavior, even though it is tethered by a line to a winch onboard an underway vessel of unknown velocity and in variable weather conditions. The predictable descent behavior is achieved by maintaining a. minimal constant tension on the line within a narrow range. The descent behavior of a probe in "near" free-fall has sufficient predictability to construct an algorithm to correlate descent time with depth.

摘要： Underwater vehicles may fix their position from GPS at the surface of the water and use bottom track for dead reckoning once it has descended to within tracking range of the bottom of a body of water. This disclosure describes a method and system for navigation through the water through depths where GPS is not available using current profiles from sonar systems including acoustic Doppler current profilers (ADCP). This extrapolation of earth referenced current profiles can provide a way to estimate vehicle motion below the surface before the vehicle reaches the bottom. Once bottom track is achieved, the corrected reference for vehicle motion improves the vehicle position estimate. A Kalman filter updates vehicle position and current profile estimates during descent, and the bottom track when the bottom comes within range to enable navigation of underwater vehicles.

摘要： Embodiments of a system and method for a forward looking sonar, for example, configured for use in an underwater vehicle, are disclosed. One embodiment includes a method of imaging a region. The method includes transmitting at least one acoustic pulse from a transducer and receiving a portion of the pulse scattered from a region. The method further includes generating a multi-channel signal based on the received portion of the pulse scattered from the region, sampling the scattering signal to generate a plurality of complex samples, and forming a plurality of beams in a horizontal plane based on the complex samples. The plurality of complex samples may be processed to obtain image data comprising angles of arrival from scattering components in a vertical plane for each horizontal beam. An image may be generated based on the image data. Other embodiments may include apparatuses such as sonar systems.

摘要： Systems and methods for measuring velocity in fluid are disclosed. In one aspect, a method (900) comprises transmitting a first set of signals of a bandwidth broader than the measuring system, receiving echoes from the first set of signals, obtaining a first velocity estimate based on the echoes, transmitting a second set of signals of a bandwidth narrower than the measuring system, receiving echoes from the second set of signals, obtaining velocity estimates based on the echoes from the second set of signals, selecting one of the velocity estimates based on the first velocity estimate. In another aspect, a method (280) comprises removing substantially a bias related to a first velocity from raw velocity estimates. In another aspect, a method (1900) comprises obtaining a velocity estimate for each of a set of transmitted pings, calculating a velocity based on the sum of the velocity estimates.
