This solution has a crucial importance on the battlefield for the survivability and the ability to minimise losses caused by fratricidal fire. The author has conducted field tests of the real equipment configuration taking into consideration the probability of identification as the main evaluation criteria instead of traditional antenna coverage diagram. The results fully confirmed the operational requirements for the designed antenna. The basic idea of design can be applied to any other antenna system, especially for secondary radiolocation devices.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130191262","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}

Due to multi-path effects and changes in the underlying coordinate systems of the involved antennas, the polarisation state of an electromagnetic wave at the receiving antenna of a mobile station is very likely to change. The presented project involves a data measurement and detailed visual investigation of these polarisation properties in the field of GSM mobile communication at the frequency band 1800 MHz. The measuring system mounted on a special car moves along a predefined trajectory around a GSM telecommunication cell. The collected data, which are received from a dual polarisation antenna, together with the information of the location, orientation and velocity of the system, which is provided by other sensors, is subsequently processed by the standard signal analysis hardware and the digital signal processing software, so that the polarisation behaviour of the received wave can be identified and visualized. The visualisation system is based on a digitized map into which the data received from GPS is inserted specifying the actual position of the measuring system. A particular polarisation state is simultaneously assigned to the position data in the digital map. The data analysis and signal filtering is performed to estimate multi-path propagation effects and to reduce the influence of them on the quality of the link. The results of this project could be for instance used in future generations of wireless mobile communication systems, where the polarisation dependent effects may contribute to increase reliability and capacity of the transmission service. This research was performed within the AMPER project, which is supported by the EU Commission.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"409 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134354185","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}

Filters and tapped-delay networks employed in conventional wideband linear arrays are avoided by using a two-dimensional rectangular array structure. In this array, only constant real-valued weighting coefficients, realized using amplifiers or attenuators, are used to form a desired radiation pattern. In order to estimate direction of arrival of a wideband signal, the MUSIC algorithm in conjunction with an interpolated array technique is applied. In the interpolated array technique, a composite covariance matrix is generated, which is a simple addition of covariance matrices of narrowband virtual arrays, being stretched or compressed versions of a nominal array. A working prototype of this wideband array is presented. Its operation is assessed via full EM simulations and measurements.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133523056","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}

Faster SAW means higher frequency operation for the same technological difficulty of making metal strips of interdigital transducers (IDTs) of micrometer width and nanometer resolution. The fastest acoustic waves are the bulk waves which cannot propagate at the substrate surface nor yield strong interaction with IDTs over longer propagation distances required in the SAW filters for narrow-band devices; the surface signal of bulk waves quickly vanish due to the wave propagation (and diffraction) into depth of the body. There is however, a remedy for it: the surface grating like periodic grooves or periodic metal strips (being these of the applied IDTs in the device), can help to trap the bulk wave at the surface making it a complex surface wave-guided mode. This phenomena is analyzed in this paper using the earlier developed spectral theory method in contrast to the couple-of-modes method presented afterwards. Here, only mechanical fields are discussed.","PeriodicalId":315003,"journal":{"name":"2006 International Conference on Microwaves, Radar & Wireless Communications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115596378","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}
