Measurement of the light backward scattering characteristics from a target with rough surface and its image processing

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

“…( 1) and ( 2), Cheng and Wang presented the laser radar equations of a pulse beam, which have been continuously revised in Refs. [27] and [28]. The power P s (t) of the pulse beam scattered by the unit area ∆A s of the target are given by…”

“…As a result, the pulse beam, as the closest theoretical model of the laser, has been brought forward in order to obtain more precise models in Lidar engi-neering applications. For the pulse beams scattered by a static target, we have derived equations to describe the light scattering of a rigid body, [27,28] and carried out laser high-range resolution profile (LHRRP) simulations. [29] It is very significant to study the motions of rough targets such as ballistic missiles, namely, translation, rotation, and vibration.…”
