摘要
Abstract
The differences of laser mean intensity on target that are induced by parameter errors are analyzed, and the effects of atmospheric parameter errors on the calculation precisions are obtained.The errors of wind velocity and aerosol absorption affect the calculation results by thermal blooming.The thermal blooming is stronger, the effects are severer.In strong thermal blooming, ±(5～8)％ wind velocity errors will induce about ±10％ calculation errors, and ± (10～20)％ errors of aerosol absorption proportion will also induce about ±10％ calculation error.In weak thermal blooming and strong turbulence, ±(5～7)％errors of turbulence coherent length will induce about ±10％ calculation error.关键词
