<p><P>PROBLEM TO BE SOLVED: To obtain a tracking receiver which is capable of suppressing reduction in the detection amount of angle errors in an azimuth angle AZ and an elevation angle EL in an environment where a C/N is low. <P>SOLUTION: Angle error calculation means is provided which calculates an angle error Az<SB POS="POST">ideal</SB>of the azimuth angle AZ with respect to a mobile and an angle error El<SB POS="POST">ideal</SB>of the elevation angle EL from an I signal and a Q signal of a baseband converted by signal conversion means. Angle error amplification means multiplies the angle error Az<SB POS="POST">ideal</SB>of the azimuth angle AZ and the angle error El<SB POS="POST">ideal</SB>of the elevation angle EL calculated by the angle error calculation means by an angle error amplification factorαcorresponding to a C/N of a SUM signal. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
