High Resolution Range Profile Identifying Simulation of Laser Radar Based on Pulse Beam Scattering Characteristics of Targets

Abstract

Abstract-This is a presentation of an innovative technique of rigid body estimation for use with laser high-range resolution profile (LHRRP) simulations. The theory of pulse beam scattering from random rough surface is used to build a theoretical model which computes simulations for the laser pulse HRRP of the whole dimension target. As two especial cases, the LHRRP of sphere and cone are simulated in detail. We discuss and analyze some influential factors on laser radar HRRP imaging such as their dimensions, correlation length and height root mean square of the rough surface, refractive index of the material and width pulse. The simulated results suggest that the reliable identifications are possible provided in some aero and aerial recognized applications with higher resolution by laser radar.

Frequency-Diversity RCS Based Target Recognition with ICA Projection

“…Simulation results show that the recognition scheme is efficient and accurate, and can tolerate noise effects. The signal processing techniques of this study can be applied to many other applications in radar engineering [7][8][9][10][11][12][13][14][15][16] or target classification [17][18][19].…”

Pulsed Beam Expansion of Electromagnetic Aperture Fields

“…The motivation to use these expansions lies in their mutual spectral-spatial (and temporal for time-dependent fields) localization and the capability to propagate the expansions' waveobjects in different complex environments. Such scalar and electromagnetic (EM) wave solutions have been obtained in anisotropic medium [8][9][10][11][12][13], dispersive medium [14][15][16][17], inhomogeneous medium [18][19][20][21][22] and for inverse scattering [23][24][25][26][27][28]. Several electromagnetic beam scattering and diffraction problems have been solved for rough surface scattering [29,30], dielectric interfaces [31,32], stratified media [33][34][35][36], and more.…”

Multi-Wavelength Fiber Optical Parametric Oscillator Based on a Highly Nonlinear Fiber and a Sagnac Loop Filter

“…This year we welcome the 50th anniversary of the laser technology, which has powered remarkable progress [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] in the past 50 years since the invention of the first laser in 1960 [19]. Fiber lasers are one kind of the most important lasers, which also include multi-wavelength fiber lasers (MWFLs) with a huge potential in applications such as WDM optical communication systems, optical fiber sensors, optical component testing, microwave photonics and spectroscopy [20][21][22][23].…”
