We study the mechanical property of a two-dimensional filament with constant spontaneous curvature and under uniaxial applied force. We derive the equation that governs the stable shape of the filament and obtain analytical solutions for the equation. We find that for a long filament with positive initial azimuth angle (the azimuth angle is the angle between x axis and the tangent of the filame...

In this paper, the aperture synthesis processing techniques for distributed shipborne high frequency hybrid sky-surface wave radar (HFHSSWR) are proposed to improve azimuth resolution and obtain velocity vector estimation of moving target. First, system geometry signal model target HFHSSWR formulated, then improvement principle is derived. Second, based on developed model, we propose an algorit...

The purpose of the article is to evaluate accuracy method determining grid azimuth using equipment consumers satellite navigation systems. Todays, there are several ways determine for topogeodetic references. However, due development in military and joint force operation, artillerists use coordinate more often. expedience has not been studied yet requires field research. So, we have already obt...

In recent years, with the rapid development of UAV industry, traditional positioning equipment has been unable to carry out effective control processing. This paper mainly studies pure azimuth passive in attempted formation flight UAV. On basis in-depth analysis signals received by receiving signal UAV, assuming that deviation position at point is under controllable error range, analyzing relat...

Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? The obtained answer is: yes. This investigation showed an agreeme...

InSAR processing usually involves two successive steps: focusing and interferometry. Most public-domain InSAR processing toolboxes are capable of performing both operations with data acquired in the standard Stripmap mode, starting from raw SAR data (level 0). However, the focusing of burst-mode data, such as TOPS and ScanSAR, requires substantial modifications to standard focusing methods due ...
