The main of them are spatial correlation of the speckle, complexity of an analyzed image and peculiarities of a method used. Spatial and spectral domain approaches are analyzed. It is shown that for both approaches spatial correlation of the speckle is to be estimated and taken into account.

The section is formed by two short rectangular inserts arranged in antipodal position in a cross section of a rectangular waveguide. Influence of changing the posts' dimensions on the section frequency response is numerically investigated. A pole generation mechanism is examined within the concept of the spectral theory of open waveguide resonators. Attenuation pole generation is demonstrated over the single-mode range and in a wide multi-mode range. It is shown that “spectral” estimations of the pole frequency and bandwidth are more precise than ones obtained within the ordinary `modal' approach. High-accuracy estimation is demonstrated in a wide frequency range.","PeriodicalId":283310,"journal":{"name":"2015 International Conference on Antenna Theory and Techniques (ICATT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128458712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The asymptotic solution of the equation was found by the generalized method of induced magnetomotive forces (MMF).
