Abstract

The integration of radar and communication systems is advantageous for improving the utilization of hardware resources and spectrum efficiency, and has become a focal point of research in recent years. The core challenge lies in designing an adaptable waveform capable of simultaneous information transmission and radar detection. In this study, the orthogonal frequency division multiplexing (OFDM) radar waveform is extended by embedding communication coding, resulting in an integrated waveform known as OFDM-Chirp. This waveform combines the high data rate advantage of OFDM communication waveforms and the high-resolution advantage of linear frequency modulation (LFM) radar waveforms. On this basis, a feasible integrated sensing and communication system scheme is constructed. Under the configuration of a general monostatic radar, key parameters such as the peak-to-average power ratio (PAPR) and communication bit error rate (BER) are analyzed. The results demonstrate that the proposed waveform exhibits excellent radar detection performance and wireless communication capability.
