Adaptive Local Polynomial Fourier Transform in ISAR
The adaptive local polynomial Fourier transform is employed for improvement of the ISAR images in complex reflector geometry cases, as well as in cases of fast maneuvering targets. It has been shown that this simple technique can produce significantly improved results with a relatively modest calculation burden. Two forms of the adaptive LPFT are proposed. Adaptive parameter in the first form i...
متن کاملFourier-Sparsity Integrated Method for Complex Target ISAR Imagery
In existing sparsity-driven inverse synthetic aperture radar (ISAR) imaging framework a sparse recovery (SR) algorithm is usually applied to azimuth compression to achieve high resolution in the cross-range direction. For range compression, however, direct application of an SR algorithm is not very effective because the scattering centers resolved in the high resolution range profiles at differ...
متن کامل(Microsoft Word - ISAR Imaging of Targets with Complex Motion Based on the Chirp Rate \250CQuadratic Chirp Rate Distribution)
In inverse synthetic aperture radar (ISAR) imaging of targets with complex motion such as fluctuating ships with oceanic waves and high maneuvering airplanes, the azimuth echo signals can be modeled as cubic phase signals (CPSs) after the migration compensation. The chirp rate (CR) and the quadratic chirp rate (QCR) are two important physical quantities of the CPS, which deteriorate the azimuth...
متن کاملBeam Propagation Method based on Fast Fourier Transform and Finite
I. INTRODUCTION THE accurate analysis, design and optimization of guided-wave structures are essential for the development of integrated photonic devices. Of all the methods used to simulate guided-wave propagation in these devices, the beam propagation method (BPM) has been one of the most popular approaches used in the modeling and simulation of electromagnetic wave
متن کاملISAR Imaging of Ship Target with Complex Motion Based on New Approach of Parameters Estimation for Polynomial Phase Signal
ISAR imaging of ships at sea with significant motion results in the Doppler frequency shift for the received signal is time-varying, which will deteriorate the ISAR image quality for the Range-Doppler (RD) algorithm. In this paper, the received signal is modeled as a multicomponent cubic phase signal (CPS), and a new method for estimating the parameters of CPS based on the integrated high-order...
