    摘要： With conventional wind measurement systems, there is the problem that an effective data acquisition rate with respect to wind vectors is low when a shield in front of a laser radar device exists.
    A data processing device of the present invention includes: a data communication device configured to communicate with a laser radar device to acquire a value of line-of-sight wind-speed, a laser emission angle, attitude information, position information, and a time; a storage device configured to store the value of line-of-sight wind-speed and the time; a central processing unit configured to run a data selector to select a value of line-of-sight wind-speed stored in the storage device and being present within a set time period from a time about the value of line-of-sight wind-speed which is newly acquired by the data communication device, and configured to run a wind vector calculator to calculate a wind vector using the value of line-of-sight wind-speed which is newly acquired by the data communication device, and using the value of line-of-sight wind-speed selected by the data selector; and a memory configured to preserve the data selector and the wind vector calculator.

    摘要： A wind velocity searching unit 30 is configured so as to, when a spectrum signal calculated by a spectrum calculating unit 22 is one in a range bin having a signal strength less than a first threshold Th 1 , determine a search center IF of the search scope for a Doppler frequency corresponding to a wind velocity in the range bin by using a wind velocity model selected by a wind velocity model selecting unit 29, and search for the wind velocity in the range bin from the spectrum signal within the search scope whose search center IF is determined thereby. As a result, the probability that the peak of noise is detected erroneously as the peak of the spectrum signal is reduced.

    摘要： A system controller 16 determines whether the quality of either a distance image or a light intensity image satisfies reference quality, and, when the quality of either the distance image or the light intensity image dos not satisfy the reference quality, outputs a speed change command to lower a speed, an altitude change command to change a submarine altitude (depth), or the like to a navigation control unit 2, thereby changing a physical relative relation between a measurement plane 3 and a device in question. As an alternative, the system controller changes a beam scanning rate f, a beam divergence θ, or the like within limits at which the amount of variation in a spatial resolution does not exceed a permissible amount.
