Chirp - definition of chirp by The Free Dictionary

WebThe target (corner reflector) is kept at a distance so that it generates an IF of around 1 MHz. The chirp parameters are chosen appropriately. A narrow-band RF sweep is chosen that sweeps in the center of the band. Narrow band is chosen to minimize the frequency-dependent beam tilt. Next, the elevation angle is swept. WebThis paper introduces the design of wide- band digital chirp signal generator, which can realize both functions of the direct frequency synthesis (DDFS) and the direct digital wave synthesis (DDWS). phonoe google maps on 213 honda accord
