چکیده
-In this investigation, the signal reflectfd by a target to the *@uency molar is _ using both nonparametic and parametric approach=. ~ au--ive movrng average (ARMA) model of the reflected signal is fmt used to estimate the location of the targets. Them an extmded Prony’s method is used to estimate the magnitude of the reflection ~mden~ of the targets. These model-w approaches are f-d to provide super resolution and improvement in target ~tion as cunpared to a conventional non-parametric approach. Several simulations are made to compare the Performances of th~ methods.

A Deep Model for Super-resolution Enhancement from a Single Image
This study presents a method to reconstruct a high-resolution image using a deep convolution neural network. We propose a deep model, entitled Deep Block Super Resolution (DBSR), by fusing the output features of a deep convolutional network and a shallow convolutional network. In this way, our model benefits from high frequency and low frequency features extracted from deep and shallow networks...
متن کاملCharacterization of the scattering centers of a radar target with polarization diversity using polynomial rooting
In this paper, we propose a new high resolution method with polarization diversity for the characterization of the scattering centers of a radar target, using a stepped-frequency radar system. The proposed method is based on the polynomial rooting technique. It allows to optimally use the information contained in the polarization of the received wave while keeping the calculation cost moderate....

A new automatic target recognition algorithm to recognize and distinguish three classes of targets: personnel, wheeled vehicles and animals, is proposed using a low-resolution ground surveillance pulse Doppler radar. The Chirplet transformation, a time frequency signal processing technique, is implemented in this paper. The parameterized RADAR signal is then analyzed by the Zernike Moments (ZM)...

متن کاملSuper-resolution of coherent targets by a directional borehole radar
In this paper, an analytical method based on the multiple signal classification (MUSIC) algorithm is applied to three-dimensional (3-D) estimation of target positions using a directional borehole radar. A cylindrical conformal array on a conducting cylinder in a borehole was used for experimental measurements estimating the position of targets. It is also shown that the algorithm provides much ...
