Abstract: An apparatus and a method for canceling an adaptive interference signal are provided to obtain an optimum erroneous alarm rate by adaptively changing an erroneous alarm rate of a CA-CFAR(Call Averaging-Constant False Alarm Rate) detector. A frequency domain conversion unit(202) receives an auxiliary channel output signal for canceling an interference signal included in a main channel output signal, and converts it into a frequency domain. A weight value calculating unit performs calculation by multiplying a certain weight value to the frequency domain-converted signal. An adaptive signal processing unit(401) discriminates whether there is an interference signal in each frequency band, and selectively updates only a frequency band signal in which there exists an interference signal through the weight value calculating unit.
