In modern electronic warfare, integration of radar and communication plays an important role in maximizing resource utilization and reducing electromagnetic interference, especially for the integrated waveform design technology based on signal sharing. In this paper, we consider orthogonal frequency diversity multiplexing (OFDM) into the design of an integrated radar and communication system with P4 complementary code serving as modulation code. An analytical expression of the ambiguity function for OFDM signal with each pulse consists of multiple consecutive symbols is derived. The idea of minimum spacing matching to demodulation is then proposed. Moreover, an integrated modelling is established, of which radar and communication performance is evaluated.
