The active reconnaissance which is based on optical system′s “cat-eye” effect is easy influenced by optical system′s aberration.A model of spherical aberration optical system′s “cat-eye” effect was established and the numerical simulation calculation method was used to analyse the relationships of target optical system′s spherical aberration with the reconnaissance laser′s echo divergence angle,the received echo power and the maximum reconnaissance distance.The results indicates that target optical system′s spherical aberration could observably increase the echo divergence angle,decrease the received echo power and the maximum reconnaissance distance.It brings bad influence to the active laser reconnaissance.
