<title>Techniques for radar imaging based on MUSIC algorithm</title>

Abstract

ABSTACT At first, the radar target scattering center model and MUSIC algorithm are analyzed. How to efficiently set the parameters ofthe MUSIC algorithm is given through a great deal of simulated radar data in experiment. After that, according to measured data oftwo kinds of plane target on filly polarized and high range resolution radar system, author mainly investigated particular utilization of MUSIC algorithm in radar imaging, two-dimensional radar images are generated for two targets measured in compact range. In the end, we draw a conclusion about the relationship between radar target scattering properties and imaging results.[Keyword] MUSIC algorithm, radar imaging, scattering center Here: R the distance from radar to reference point F the frequency ofradar emitting signal SK the intensity ofthe kth scattering center C-----the free space speed of light 9 target bearing angle (Xk, k )----the location coordinates of the kth scattering centerOnce reference point is set, R is known, For the convenience of analysis, we leave out R, then (1) can be written as: 168 SPIE Vol. 3545 • 0277-786X1981$10.00 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/17/2015 Terms of Use: http://spiedl.org/terms
