Abstract

General model is established for the echo signal of a target with micro-motion. Then time-frequency analysis and Hough transform are utilized for motion parameter estimation and radar signature extraction in terahertz band, and the estimation of reflection coefficients of scatterers is completed through NLS and CLEAN algorithm. The simulation result shows that this method of Hough transform has the advantages of high precision and strong anti-noise. The model of echo signal and method of parameter estimation are useful for radar target detection and identification. © 2012 Springer Science+Business.
