Embodiment Construction

[0052]According to the MIE theory, the particle size distribution function PSD (PSD: Particle Size Distribution) is used as input, and the volumetric scatter function in the scattering angle (0.1 ° -90 °) range is established. The slope of the PSD is calculated based on the dual curve slope calculation of the particle attenuation spectrum measured in different waters. It is very convenient to measure the measurement of the PSD, which can be measured by providing a commercial instrument for high sample rate data. The scattering angle (0.1 ° -90 °) is divided into (0.1 ° ≤ ψ ≤ 5 °) and (5 ° ≤ ψ ≤ 90 °), and then the particle volume scatter function in water is molded in these two ranges. .

Abstract

The invention discloses a channel characteristic modeling method for an underwater wireless optical communication system, which comprises the following steps of: establishing an underwater particle volume scattering function with a scattering angle in a range of 0.1-90 degrees by taking the slope and the refractive index of a particle size distribution (PSD) function as input according to a Mie theory; then, dividing a scattering angle range into two ranges, and respectively modeling a volume scattering function of particles in water; according to the method, various inherent optical properties of the aquatic particles are calculated and analyzed, the relation among the backscattering ratio, the refractive index and measurable optical parameters is deduced, the volume scattering function is improved, and the model is further used for calculating the refractive index and scattering model of some specific ocean and coastal water areas. And the underwater transmission characteristics of the light can be estimated more accurately.

Description

Technical field [0001] The present invention belongs to the field of underwater wireless optical communication, and in particular, the present invention relates to an underwater wireless optical communication system channel characteristic modeling method, electronic device, and storage medium. Background technique [0002] In order to meet the rapid growth of underwater human activities, the demand for high transmission rates, large bandwidth underwater data communication links are growing. At present, water sound communication and RF communications have been widely used in underwater communication. However, the transmission rate generated when the sound wave is used, and the transmission rate of the acoustic wave is limited, which limits the amount of data that can be transmitted by the water sound communication. Radio frequency communication, its communication distance and communication rate is difficult to balance, and long-distance communication is necessarily lowered. Wirele...
