The purpose of the present invention is to provide a receiver of a seeker wherein the dynamic area of a received signal can be expanded, and the receiver is robust to noise and can be realized in a small size and at low costs. Disclosed is receiver for a W-band seeker. The present invention comprises: an ultrahigh-frequency reception part for having an analog received signal in the W band, which is received through at least one receiving antenna, applied thereto, generating a local signal and synthesizing the received signal and the local signal, thereby downward converting the received signal into a received signal in a designated intermediate frequency band; an AD converter for having the received signal, which has been downward converted into the intermediate frequency band, applied thereto and converting the same into a digital signal, thereby generating a digital received signal; a digital reception part for having the digital received signal applied thereto, generating a digital local signal and synthesizing the digital received signal and the digital local signal, thereby converting the same into a digital received signal in a base band; and a signal processing part for having the digital received signal in the base band applied thereto and analyzing the same via a preset method, thereby detecting a target. |
