Study on error of non-line-of-sight light propagation by single-scattering model;

Based on the assumption of single-scattering,atmospheric propagation model of non-line-of-sight optical scattering communication system is studied.

A simple proportional relationship is established between the higher scattering and the single scattering by analyzing each level scattering of the multiple backscattering lidar received signals.

A NLOS (Non line of sight) high-resolution location algorithm is proposed based on the parameters TOA(Time of Arrival) 、DOA(Direction of Arrival) and DOD (Direction Of Departure) of multiple propagation paths, which can be measured simultaneously under the scenarios where single scattering is dominant in the double-array mobile communication system.

Based on the single scatter model (Aki), using 26 earthquake digital wave data above ML≥2.

Then the scattering field,the scattering parameter and the equivalent impedance are obtained.

Auger recombination,and model of calculating scattering parameter (S-Parameter) is established.

An improved numerical algorithm of Mie scattering parameter is presented in this paper.

Then, scattering parameters of circular groove to rectangular waveguide junction were calculated.

Two novel equivalent methods,namely predication method and evaluation method,which can be used to analyze the influence of through-hole(TO) packaging on the high frequency response of laser diode,are deduced from the relation between the scattering parameters of laser diode before and after packaging.
