Channel Error Compensation for Multi-channel SAR Based on Cost Function(in English)

Autor: Zhang Lei, Deng Yun-kai, Wang Yu, Zheng Shi-chao, Yang Liang

Publikováno v: Leida xuebao, Vol 3, Iss 5, Pp 556-564 (2014)

Multi-channel in azimuth is a technique to achieve high-resolution as well as wide-swath in Synthetic Aperture Radar (SAR) systems. Channel error is inevitable in multi-channel systems and it induces blurring in subsequent SAR imagery. Existing compe

A SAR Back Projection Autofocusing Algorithm Based on Legendre Approximation

Autor: Gao Yang, Yu Wei-dong, Feng Jin, Zheng Shi-chao, Yang Liang

Publikováno v: Leida xuebao, Vol 3, Iss 2, Pp 176-182 (2014)

The Back Projection (BP) algorithm is a very important time-domain methodology for Synthetic Aperture Radar (SAR) imaging. However, conventional autofocus techniques are based on frequency-domain imaging algorithms, and can not be directly applied to

Error Analysis of Fast Moving Target Geo-location in Wide Area Surveillance Ground Moving Target Indication Mode

Autor: Zheng Shi-chao, Song Hong-jun, Liu Ya-bo, Yan He, Wu Kun

Publikováno v: Leida xuebao, Vol 2, Iss 4, Pp 445-453 (2013)

As an important mode in airborne radar systems, Wide Area Surveillance Ground Moving Target Indication (WAS-GMTI) mode has the ability of monitoring a large area in a short time, and then the detected moving targets can be located quickly. However, i
