摘要： An S/N calculation circuit 12 to calculate the S/N ratio of a received signal, and an S/N comparison circuit 13 to compare the S/N calculated by the S/N calculation circuit 12 with a threshold Th are disposed, and a parameter setting circuit 14 controls the radiation state of a beam radiated from a transmission optical system 5 according to the result of the comparison performed by the S/N comparison circuit 13. As a result, even if the state of the propagation environment gets worse, degradation in the communication quality can be prevented and communicative stabilization can be achieved.

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.

摘要： The laser radar device (1) includes: a modulated light generator (10, 11) configured to generate modulated laser light using frequency modulation based on a control parameter; an optical combiner (15) configured to combine the received light and the local light to generate interference light; a photodetector (20) configured to detect the interference light and output an electrical signal; a frequency-to-voltage converter (31) configured to convert the electrical signal into a voltage signal; a characteristic calculator (32) configured to measure a characteristic value of the voltage signal; an evaluator (33) configured to evaluate, on a basis of the characteristic value, whether a center frequency of a spectrum of a return signal component is within a range of a demodulation band of a demodulation circuit (21); and a parameter setting unit (34) configured to change the control parameter when it is evaluated that the center frequency is not within the range of the demodulation band.
