Abstract
A tracking receiver includes: a complex sum signal generator to generate a complex sum signal; a complex difference signal generator to generate a complex difference signal; a first correction coefficient storage to store a first correction coefficient represented by a complex number; complex difference signal correcting circuitry to calculate a corrected complex difference signal by correcting the complex difference signal based on the complex sum signal and the first correction coefficient; and an orientation direction error calculator to calculate an orientation direction error based on the corrected complex difference signal and the complex sum signal, the orientation direction error being a difference between an arrival direction and an orientation direction, the arrival direction being a direction from which the radio wave comes and arrives, the orientation direction being a direction in which the antenna is orientated.
