<p>The present invention proposes an apparatus for cancelling frequency interference, which unifies and supplies a switching frequency of each switching regulator. A first embodiment of the proposed apparatus includes: a first SMPS which generates a first switching frequency signal using an embedded clock generator, and supplies electricity to a vehicle radar system by using the first switching frequency signal; a second SMPS which supplies electricity to the vehicle radar system together with the first SMPS by generating a second switching frequency signal; and a signal processing part which performs signal processing of a reflected wave reflected from a target, and cancels a frequency interference component between the first switching frequency signal and the second switching frequency signal by using an output obtained by signal processing of the reflected wave. According to the present invention, the apparatus can prevent error detection of the vehicle radar apparatus by removing unwanted frequency interference components in the vehicle radar apparatus, that is, a first sum/subtraction frequency component and an IMD frequency component, fundamentally.</p> |
