title = "Performance Analysis of Radar Communication Shared Signal Based on OFDM",
abstract = "Orthogonal Frequency Division Multiplexing (OFDM) signal is proved to be an appropriate shared signal in Integrated Sensing and Communication (ISAC). In this paper, an OFDM waveform with radar and communication functions is proposed, which is obtained by the traditional OFDM communication signal pulse processing. In order to measure the radar resolution performance of the shared signal, the effects of the number of subcarriers Nc and OFDM symbols Ns on the performance of radar ambiguity function (AF) are analyzed. Meanwhile, the influence of cyclic prefix (CP) on range ambiguity function is also considered. The results show that the inherent range resolution and inherent velocity resolution of shared signal are inversely proportional to the signal bandwidth and pulse width, respectively; The sidelobe characteristics of the velocity ambiguity function and range ambiguity function can be improved by adding the number of Nc and Ns, respectively. In addition, using zero padding (ZP) can eliminate the influence of CP on the range ambiguity function.",
