A compensation apparatus is provided which performs a compensation process of removing an image component in a quadrature-demodulated signal. The compensation apparatus includes a quadrature demodulation compensation section that compensates for the quadrature-demodulated signal including an I signal and a Q signal. The quadrature demodulation compensation section is configured to perform a compensation process of compensating for a characteristic difference between the frequency characteristic of a first filter that performs filtering of the I signal and the frequency characteristic of a second filter that performs filtering of the Q signal.
