The Fourier transform has been widely used in ISAR signal and image processing. In most cases, ISAR signals exhibit time-varying behavior in the Doppler spectrum. Thus, a joint time-frequency analysis (JTFA) for ISAR signals is more useful. In this paper, we introduce a new WVD algorithm jointed CLEAN technique. Meanwhile, the simulations of LFM signal in ISAR are adapted to compare their performance...
Motivated by the development of MIMO communication, Multiple-Input Multiple-Output (MIMO) radar has drawn considerable attention. Currently, most articles about MIMO Radar analysis focus on angle diversity, the article investigates principal component analysis used in MIMO Radar detection, further studies the performance of transformation of logarithm as its improvement. The simulation results indicates...
A new approach for parallel implementation of synthetic aperture radar (SAR) imaging is presented. This approach is based on time domain correlation (TDC) which reconstructs radar imaging in spatial domain via Fourier transform using wave equation inversion theory. TDC algorithm can be modified for parallel implementation since it reconstructs images via matched filtering without any need for approximation...
To simulate synthetic aperture radar (SAR) raw data of extended scenes in the presence of arbitrary trajectory deviations, an efficient simulation scheme based on parallel computation in hybrid domain is proposed. We firstly present a novel target-to-antenna distance model which takes the three-dimensional components of the trajectory deviations into consideration. Then a general and compact hybrid...
Synthetic aperture radar has been used widely since it can provide high-resolution images. Many imaging methods have been proposed based on Fresnel approximation. These imaging methods are not applicable when synthetic aperture radar works at near field because the Fresnel approximation is completely wrong. Time domain correlation is a kind of digital reconstruction in spatial domain via Fourier transform...
