The paper deals with considering a problem typical for lossy compression of remote sensing images. While compressing an image under interest by DCT-based coders which are rather efficient it is desirable to predict what CR will be attained for a given quantization step. We show that such prediction is possible and it can be done easily, quickly, and quite accurately. Moreover, prediction can be done for practically noise-free images and images corrupted by unknown type of noise with unknown characteristics. Influence of noise type and image properties is briefly studied.

In this paper we present an experimental method of determining losses caused by 1D gratings based on applying those gratings as output couplers of THz lazers. Firstly we experimentally determined the optimal coupling coefficient for two types of gratings: wire gratings and strip gratings on dielectric substrates. Therefore we determined the value of total losses in laser cavity for each researched grating. Comparing these results it is possible to determine the losses caused by specific grating.

Multichannel time integrating correlator has been implemented in FPGA Xilinx Virtex 6 using X6-1000M board from Innovative Integration Inc. A new implementation of relay correlator for FPGA has been suggested and tested. The approach suggested enables exclusion of multipliers usage that saves FPGA resources, which, in particular, allows increasing of the working range of Noise Radar. The developed correlators have performances sufficient for design of noise radar according to the software defined radar concept, such as homeland security sensors, ground based SAR, and radar tomography enabling generation of 2D and 3D coherent SAR images and radio-films.

We address a novel neural network (NN) computing-based approach to the problem of feature enhanced (FE) fusion of remote sensing (RS) imagery acquired with different coherent radar/SAR sensing modalities. The novel proposition consists in adapting the Hopfield-type maximum entropy NN (MENN) computational framework to solving the FE image recovery inverse problems with adaptive multiple sensor data fusion that preserves salient radar/SAR image features. The FE fusion is performed via aggregating the descriptive experiment design and the theoretical informatics inspired maximum entropy regularization frameworks for iterative minimization of the energy function of the multistate MENN with adaptive adjustments of the MENN's synaptic weights and bias inputs. We also feature on the computational implementation issues of the MENN-based multi-sensor radar/SAR data fusion and verify the overall image enhancement efficiency via computer simulations with real-world RS imagery.

Preliminary results of the comparative analysis of Quantum Radar (QR) based upon quantum entanglement phenomenon and Noise Radar (NR) based upon classical coherence notion and correlation processing of random signals are presented in the paper. It has been shown that the basic idea of entangled multi-photon QR for simultaneous implementing of high penetrating ability of the entangled photons and high spatial resolution performance does not work because of decay of entangled state of the transmitted photons when they hits a wall, for example. QR operation abilities may be described in terms of classical physics. In addition, the multi-photon QR has been modeled by means of classically phase locked multi-frequency signals (regular and chaotic). Results of computer simulation of basic properties for such radar are presented.

This paper presents the design of a compact 11-dB coupled-line directional coupler operating at center frequency of 1.2 GHz, which features improved frequency characteristics. A compact size of the coupler has been obtained by utilization of high-permittivity dielectric substrate while high performance has been ensured by application of method for the design of quasi-ideal coupled-line sections. Moreover, the circuit has been realized on alumina ceramic (Al2O3) substrate using thick-film technology what allows for low-cost and easy integration with passive and active circuits into hybrid microwave integrated circuit (MIC). The proposed circuit has been electromagnetically verified, manufactured and measured. The obtained results proved the usefulness and performance of the presented circuit.

We report on recent developments of the conception of all-dielectric planar metamaterials that are capable to support high-Q trapped-mode resonant excitations. A set of new designs of metamaterials are proposed and configurations of the unit cell allowing trapped-mode resonances are discussed. Advantages of the proposed designs to manifest high-Q resonant regime providing a concision choice of the degree of structural asymmetry within the unit cell are revealed.

In image processing the Super-Resolution (SR) has played an important role by acquiring High-Resolution (HR) images from the corresponding Low-Resolution (LR) images. In this paper, a Super-Resolution technique for satellite images is proposed but it can be used on images of different nature. In the current proposal to achieve a HR image, it is necessary an intermediate step, which consists in performing an initial interpolation, then features are extracted from this initial image, here, it is necessary to reduce the information obtained by the features extraction via principal component analysis (PCA). Patches are extracted from the initial image and the reduction via PCA. For each patch, the sparse representation is obtained and then, it is used to recover the HR image. By using the quality objective criteria PSNR and SSIM, the proposed technique is evaluated and shows a superiority in comparison against other existing proposals.

Directivities of linear and plane homogeneous antenna arrays consisting of different radiators were simulated in the MathCad environment when distance between the radiators and numbers of radiators were varied in the wide limits. Antenna arrays with linear, rectangular and square aperture were considered. The highest attainable directivity of the antenna array with given numbers of radiators was determined. It was shown that the antenna arrays distort shapes and spectra of transmitted and received signals when the signal wavelengths are shorter than the distance between the radiators.
