Design and implementation of modulator of a novel rader waveform compatible with communication

How to generate a waveform that can realize communication of data and detection of radar at the same time is a key technology of radar-communications integration. In this paper, with the use of existing theory that proposes a novel compatible waveform by modulation LFM signal by MSK, the digital orthogonal modulation MSK-LFM signal is realized on FPGA; and the high-speed DAC and multi-channel synthesis are applied to directly generate wave at UHF-band wave. The algorithms and hardware of the modulator are discussed in detail and the test data is also given.
