Multiview ISAR Imaging for Complex Targets Based on Improved SBR Scattering Model

نویسندگان

چکیده

A novel multiview inverse synthetic aperture radar (ISAR) imaging method is proposed to simulate high-resolution and identifiable ISAR image of complex targets by handling large-angle wide-bandwidth scattering data. The data are simulated with the shooting bouncing ray (SBR) method. bidirectional ray-tracing algorithm developed reduce computation time. Simulation results indicate that improved efficient reliable calculate electromagnetic (EM) electrically large targets. To implement after simulation, we divide into subaperture conduct processing for each datum locally. Transforming global coordinate system summing them together will produce meaningful database set up automatic target recognition (SAR ATR). final simulation images further validate great performance our calculation

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Fast Isar Image Simulation of Targets at Arbitrary Aspect Angles Using a Novel Sbr Method

We present an efficient way to generate the inverse synthetic aperture radar (ISAR) image of a target at an arbitrary aspect angle using the shooting and bouncing ray (SBR) method, which is much faster than the conventional approach by inverse Fourier transforming the computed scattered fields over frequency and aspect domain. We propose a general image-domain ray-tube integration formula, whic...

ISAR Imaging using Doppler Processing Algorithm for Moving Targets

Inverse Synthetic Aperture Radar (ISAR) is used to produce high resolution imagery of non-cooperative targets by retrieving the relative motion parameters of a target with respect to a reference. This concept of estimating motion parameters is applied for obtaining cross-range resolution in ISAR imaging in which one component is produced by the relative motion between the radar and the target a...

Interferometric ISAR Imaging Based on Compressive Sensing

Inverse Synthetic Aperture Radar (ISAR) images are often used for target classification and recognition applications. However, conventional 2D images do not provide the height information about the scattering centers. In this paper, an interferometric ISAR imaging method based on compressive sensing (CS) is proposed that is able to estimate the scatterering centres heights. The interferometric ...

(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...
