HRR Profiling on Integrated Radar-Communication Systems Using OFDM-PCSF Signals

Abstract EN

In order to improve both the transmission data rate and the range resolution simultaneously in integrated radar-communication (RadCom) systems, orthogonal frequency-division multiplexing with phase-coded and stepped-frequency (OFDM-PCSF) waveform is proposed.

A corresponding high resolution range (HRR) profile generation method is also presented.

We first perform OFDM-PCSF waveform design by combining the intrapulse phase coding with the interpulse stepped-frequency modulation.

We then give the ambiguity function (AF) based on the presented waveforms.

Then, the synthetic range profile (SRP) processing to achieve HRR performance is analyzed.

Theoretical analysis and simulation results show that the proposed methods can achieve HRR profiles of the targets and high data rate transmissions, while a relative low computational complexity can be achieved.
