Unfortunately the presence of speckle degrades target detection dramatically therefore denoising algorithms are necessary. Moreover sometimes other operations, such as incoherent averaging for instance, are used to increase the Constant False Alarm (CFAR) performance. Any operation as a consequence changes the background clutter model and often it is not possible to describe it in a closed and manageable mathematical form, therefore a direct solution of the Neyman-Pearson problem is not feasible and a suboptimal criterion, such as Exponential or Gamma-distribution clutter model etc., is usually adopted. A consequence of the suboptimal global clutter model choice is the reduction of the information content of the SAR images which can affect classifier performance heavily. This paper hence is concerned with a novel mathematical approach for a local approximation of the filtered SAR image Cumulative Density Function (CDF) in order to preserve/maximize the information content carried by a SAR/ATR system.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117121724","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}

Such antennas can be used instead of standard multisector antennas. The multiuser beam-free method implies that coverage area is not divided into cells with different frequencies. Instead, all the users can use all the frequencies and active array selects signals by their position. The comparison of the standard multisector antennas with the beam-free array consisting of the same number of elements shows that the capacity (number of users operating on the same frequency) increases up to 2 times as against 6-sector antenna and 3 times as against 3-sector. Also the beam-free antenna is easily flexible. To increase the capacity it is just sufficient to add antenna elements without construction changing.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121285560","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 hyperbola feature in B-Scan data is a very important feature for GPR object detection. In this paper, a novel method based on cross correlation between adjacent A-scans is proposed to detect reflection hyperbola. The method includes four steps. B-scan data is firstly preprocessed to suppress clutters. Then, the reflection hyperbola is extracted based on cross correlation. An approach of feedback is presented to fit the extracted hyperbola. At last, Hough transform is adopted to determine whether there is an object or not.

In this paper we show how the geometric features of a multistatic radar system can be used to obtain both translational and rotational motion with a multilateration approach. While many monostatic approaches in open literature attempt to estimate parameters for a pre-assumed form of motion, our approach aims to be as general as possible. Capabilities and limitations for several implementation techniques of the multilateration method are examined and illustrated in simulations.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133626511","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}
