Doppler shift of a laser pulse beam scattered by a rotating cone and cylinder

摘要: Based on laser radar equations, a Doppler shift model of pulse beam scattered by rotating arbitrary convex target is reported in this paper. The boundary relations between an incident and the detected area elements are analyzed geometric methods. characteristics cone cylinder discussed difference plane wave from same compared accordingly. Numerical simulations show that tightly relevant to their dimensions, speeds, so on. In incidence conditions, have peak values bandwidth. If waist radius larger, value higher, shifts proportional speed target. By virtue our theoretical model, we probe into beam, which would benefit identification national defense.
