Abstract :
Requirements for signal transmission rate and ACPR in UAV multi-target data link, the method of ramped CP-2FSK modulator is given which is based on direct digital synthesis technology, and the function of the ramped CP-2FSK is implemented with hardware circuit, the ramped CP-2FSK modulation signal meeting the ACPR indicator is got. The transfer application of UAV multi-target data link shows that: the modulator is of stable performance, meeting the design requirements for ACPR of channel frequency division in UAV multi-target data link, and achieving the aim of a number of UAV flying at the same time.
