Abstract
Recently, many satellite systems have started to employ reflective-array compressors (RAC) to demodulate efficiently their M-FSK communication signals. Because the RAC´s time delay varies with temperature, pilot-tones are usually introduced as the operational reference. In this letter, the basic chirp Fourier transform (CFT) is briefly reviewed. Then, an investigation into possible pilot-tone interference caused by various chirp signals with the RAC´s dispersive delay properties is presented and discussed.
