WebThe center frequency of the chirp is f c, the chirp rate is K, and the signal bandwidth is B = K. If we transmit this signal at time t = 0, we will receive a signal from a point scatterer that is a distance R away after a time t R, where t R = 2R/c (D-4) This received signal can be written as v r (t) = v(t – t R) (D-5) (t) t 1 2 for – /2 t ... WebAbstract—The matched filter is one among many effective techniques used to maximize the signal –to- noise ratio (SNR) of chirp radar signals. Besides this enhancement in SNR, it has a drawback due to sidelobe levels which degrade the filter response. There are many additional techniques which reduce these levels
