Abstract
The technique of laser range-Doppler image has been intimately noticed by aerospace and national defense circles. A analytical model of laser range-Doppler image of cone-cylinder combination is proposed in this paper. The analytical model includes the contribution of disk base. The analytical model can provide the effects of geometry parameters, the roughness of the surface, attitude, and pulse duration on laser range-Doppler image. This analytical model can reduce into the analytical model of range-Doppler image of cone and cylinder. This analytical model can reduce into the analytical model of Doppler spectra for plane waves. The influences of geometry parameters, and attitude are analyzed numerically by using the analytical model. The results indicate that the laser range-Doppler image of cone-cylinder combination can show the information about geometrical shape and attitude of target. Combining the theory and measurements, the analytical model can be used for indentifying physical parameters and geometrical parameters of cylinders, cones and cone-cylinder combination. This analytical solution is of significance for the laser Doppler velocimetry and ladar applications.
