This paper considers the sampling of temporal or spatial wide sense stationary (WSS)
signals using a co-prime pair of sparse samplers. Several properties and applications of co …

Range cell migration (RCM) correction and azimuth spectrum being contained entirely in
baseband are critical for ground moving-target imaging (GMTIm). Without the azimuth …

In this paper, a truly sub-Nyquist sampling method for frequency estimation of sinusoidal
signals in noise is presented. Basically speaking, sinusoidal signals are first sampled at …

Chinese remainder theorem (CRT) reconstructs an integer from its multiple remainders that
is well-known not robust in the sense that a small error in a remainder may cause a large …

In synthetic aperture radar (SAR) imaging of a ground moving target, long-time coherent
integration may effectively improve the imaging quality, whereas the imaging performance …

This paper proposes a new method to focus a ground moving target with complex motions
and estimate its motion parameters in a synthetic aperture radar (SAR) system. In this …

Detection and imaging of multiple moving targets is a challenging task, particularly with real
synthetic aperture radar (SAR) data. In this paper, moving targets with different motion …

The Chinese remainder theorem (CRT) allows to reconstruct a large integer from its
remainders modulo several moduli. In this paper, we propose a robust reconstruction …

In this paper, a new algorithm is presented to image ground moving targets in a synthetic
aperture radar (SAR) system based on range frequency reversal transform-fractional Fourier …

As a wideband radar system, synthetic aperture radar (SAR) may conflict with several
electromagnetic systems. These signals may severely interfere with SAR image quality …
