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. WebChirp is a measure of the change in transmitter optical frequency as the transmitter is modulated. Chirp is often expressed by the alpha term, where j is the optical phase of … simphony sims 4 https://kungflumask.com
