【摘要】：本文在收發(fā)光軸共面的紫外光單次散射鏈路模型基礎(chǔ)上,分析了收發(fā)光軸非共面時(shí)紫外光單次散射鏈路模型,推導(dǎo)了收發(fā)光軸非共面時(shí)收發(fā)光錐在空中相遇時(shí)形成的共同散射體體積的近似推導(dǎo)公式。分析了三種非共面的情況,第一種是收發(fā)任一端沒(méi)有準(zhǔn)確朝向?qū)Ψ綍r(shí)的鏈路模型,第二種是收發(fā)光軸均偏向同一側(cè)的鏈路模型,第三種是收發(fā)光軸偏向不同側(cè)情況下的鏈路模型。通過(guò)對(duì)三種情況下接收功率的仿真分析得到,前兩種情況均可以進(jìn)行通信,但接收功率不會(huì)很高,第三種情況基本不能通信,因?yàn)楹茈y在空中形成共同散射體。
[Abstract]:Based on the single scattering link model of the transceiver optical axis, this paper analyzes the single scattering link model of ultraviolet light when the transceiver axis is not coplanar. The approximate formula of the volume of the common scattering body formed when the transceiver optical axis is not coplanar is derived. In this paper, three kinds of non-coplanar link models are analyzed. The first is the link model where the transceiver has no accurate orientation to the other, and the second is the link model in which the optical axis of the transceiver is biased to the same side. The third is the link model with different side bias of the transceiver optical axis. Through the simulation analysis of the received power in three cases, it is found that the first two cases can communicate, but the receiving power is not very high, and the third case is basically unable to communicate, because it is difficult to form a common scatterer in the air.
