Radar communication integration is one of the development directions of multifunctional combat systems. Design of integrated signal that can realize radar and communication functions is the main method to build an integrated system. In this paper, a constant envelope OFDM-Chirp integrated signal based on phase coding (CE-PC-OFDM-Chirp) is proposed. By analyzing the ambiguity function of the signal, the simulation results show that the proposed integrated signal has low distance sidelobe, narrow velocity main lobe and good error performance.
