Abstract: Integration of radar and communication on the electronic war platform is an effective method to reduce their volume, electromagnetic interference. In allusion to the periodicity of sequence, doppler tolerance, and echo-eclipse issue in suitable waveforms design of integrated radar and communication based on poly-phase pseudorandom sequence, the sharing signal based on complete complementary code which has short periodicity, high peak sidelobe ratio is proposed in integrated system, and the proposed expanding scheme of complete complementary code in paper has low computational load. Theoretical analysis and computer simulation show that sharing signal based on poly-phase pseudorandom sequence have the characteristic of excellent correlation、large doppler tolerance and anti-echo eclipse, and can satisfy signal design requirement of integrated radar and communication.
