【期刊论文】Complex ISAR Imaging of Maneuvering Targetsvia the Capon Estimator
吴仁彪, Zheng-She Liu, Member, IEEE, Renbiao Wu, and Jian Li, Senior Member
IEEE TRANSACTIONS ON SIGNAL PROCESSING, VOL. 47, NO.5, MAY 1999,-0001,():

An inverse synthetic aperture radar (ISAR) can be used to produce high-resolution images of moving targets of interest by utilizing the relative motion between the target and the radar and by transmitting signals with large bandwidth. Most ISAR imaging algorithms are based on the range-Doppler processing, which implies that the Doppler shifts remain constant during the coherent integration time. For maneuvering targets, the Doppler shifts are time varying. In this case, the algorithms will produce blurred images. We present herein an adaptive Capon spectral estimation algorithm for the complex ISAR image formation of maneuvering targets. It is an efficient recursive implementation of the well-known Capon complex spectral estimation algorithm by using FFT and simple matrix operations.

【期刊论文】Clutter suppression and moving target parameter estimation for airborne phased array radar
吴仁彪, Nanzhi Jiang, Renbiao Wu, Guoqing Liu and Jian Li
ELECTRONICS LETTERS 2nd Mrach 2000 Vol. 36 No.5,-0001,():

It is demonstrated through simulations that a combination of the vector auto-regressive (VAR) filtering technique and a maximum likelihood (ML) parameter estimation method is an effective means for carrying out clutter suppression and parameter estimation, and being more robust against system mismatches than conventional displaced-phase-centre-antenna (DPCA) processing.

【期刊论文】Autofocus and super-resolution synthetic aperture radar image formation
吴仁彪, R.WU and J.Li
IEEE Proc-Rodar, Sonar Naving., Vol. 147, No.5, October 2000,-0001,():
-1年11月30日
An FFT (fast Fourier transform) based parametric algorithm. rcferred to as MCCLEAN. is devised tor cross-range phase error compensation in SAR (synthetic aperture radar) imaging. It can be used as an independent autofocus approach for the SAR imaging of a large scene. The authors also present a similarly structured algorithm for simultaneous autofocus and super.resolution SAR image formation of a small scene or small region of interest (ROl) in a large scene. Examples are provided to illustrate the performance of the proposed algorithms
