Research on Waveform Design of Multi-Carrier Phase Coded and Frequency Modulation Signal

The composite waveform of multi-carrier phase coded and frequency modulation signal is an effective method to solve the integration of radar sensing and wireless communication. This paper mainly discussed three different types of waveforms: multi-carrier phase coded signal (MCPC), linear frequency modulation (LFM) in phase coded waveform, complex modulation of multi-carrier phase coded and frequency modulation Signal. In order to suppress radar interference and various clutter, a novel complex modulation waveform of MCPC and LFM using orthogonal frequency division multiplexing (OFDM) is designed. Signal models, formula expression and time-frequency characteristics are analyzed comprehensively for all of the conventional and novel waveforms. Numerical simulations and practical applications show that it can achieve good performance for anti-jamming and clutter suppression in the field of radar and communication by using the proposed complex modulation waveform.
