Moving Target SAR Imaging Using Planar Arrays And Multidimensional Chinese Remainder Theorem (MD-CRT)--Part I: A General Framework

Guangpu Guo, Xiang-Gen Xia

In this two-part paper, we investigate synthetic aperture radar (SAR) moving target imaging using planar antenna arrays. For a target moving over a three-dimensional terrain, its a…

Robust Multidimensional Chinese Remainder Theorem (MD-CRT) with Non-Diagonal Moduli and Multi-Stage Framework

Guangpu Guo, Xiang-Gen Xia

The Chinese remainder theorem (CRT) provides an efficient way to reconstruct an integer from its remainders modulo several integer moduli, and has been widely applied in signal pro…

A Generalized Multidimensional Chinese Remainder Theorem (MD-CRT) for Multiple Integer Vectors

Guangpu Guo, Xiang-Gen Xia

Chinese remainder theorem (CRT) is widely applied in cryptography, coding theory, and signal processing. It has been extended to the multidimensional CRT (MD-CRT), which reconstruc…

A Construction of Pairwise Co-prime Integer Matrices of Any Dimension and Their Least Common Right Multiple

Guangpu Guo, Xiang-Gen Xia

Compared with co-prime integers, co-prime integer matrices are more challenging due to the non-commutativity. In this paper, we present a new family of pairwise co-prime integer ma…
