AI Technical Summary
In complex marine environments, existing technologies cannot adaptively select the length of the photon counting velocimetry sequence, resulting in decreased velocimetry accuracy or algorithm non-convergence, and failing to effectively suppress the time-varying cumulative effect of the flow field and ensure the signal-to-noise ratio.
By extracting the time-domain statistical features of photon sequences, the length of the photon-counted ocean current velocity measurement sequence is dynamically optimized. By combining photon count density, time-varying perturbation factor of the current field, and detector dead time, a joint optimal data length objective evaluation function is constructed to achieve adaptive photon sequence truncation and complete 1-bit compressed sensing reconstruction.
In different marine environments, the photon sequence length is automatically adjusted to improve velocity measurement accuracy and algorithm convergence, suppress spectral broadening, and ensure signal-to-noise ratio and inversion accuracy.
