Research On Laser Doppler Range Imaging Theoretic And Appliance Of Quadric Revolving Body And Image Display

Target laser scattering is important to the feature extraction and identification of target. Themain contents of this paper include: triangular patch modeling based on data points, laserscattering properties of the quadratic revolution body, include ray-tracing, backscatteringtwo-dimensional intensity image, laser backscattering cross section, range-resolved laser radarcross section, one-dimensional and two-dimensional range profile, backward Doppler spectra ofmoving quadric revolution body and backward range Doppler imaging. The main results of thispaper include:1. established the ray-tracing algorithm of the quadratic revolution body, thevanishing procedure can be achieved throng this algorithm about the scattering properties ofnon-convex quadratic revolution body; Two-dimensional backward scattering imaging generalmodel for moving quadratic revolution body is established based on this;2.Establish the formulafor backward laser radar scattering cross section and range-resolved laser radar cross section ofmoving quadratic revolution body; The laser two-dimensional range image general model isestablished based on this;3.proposed the analysis model of laser backward Doppler spectra andlaser range Doppler spectra. The laser range Doppler image for cone-column combination object isachieved.4. Builded the general model of laser one-dimensional range image. The influence ofsurface material, shape, objective altitude and laser pulse width is studied in detail. The results ofthis paper have important meanings for theory study and applied value to laser scattering imagingtechnology of moving quadric revolution body.
