   Sammanfattning : A solar twin is a star with characteristics very similar to those of the Sun. This is, a Sun-like star. Earlier studies show that M67-1194 is one of the best solar twins found to date. But this star is not exactly like the Sun. LÄS MER

3. 2. Direction of arrival estimation : A two microphones approach

   Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Carlos Fernández Scola; María Dolores Bolaños Ortega; [2010]
   Nyckelord :direction; arrival; estimation; microphones; least; mean; square; fft; angle; matlab;

   Sammanfattning : This thesis presents a solution to the problem of sound source localization. The target lies in getting the direction of a source by capturing its sound field with two omni-directional microphones. The solution allows the source to be either located at a fixed location or it can be in motion within a specified area. LÄS MER
