要約(英語): In recent years, short-range radar such as automotive radar has been attracting attention. In the radar, transmission method and signal processing achieve a high range resolution and long range detection performance is required. In this paper, we propose the Stepped Multiple Frequency CPC Radar that is expected to achieve a high range resolution and long range detection performance. In the proposed method, the transmission sequence and the phase correction process expected to suppress the inter symbol interference and reduce the effects of Doppler frequency. A simulation result on the side-lobe level of CPC pulse compression is shown to verify the effectiveness of the method on the effect of Doppler shift. The other simulation result is shown to verify the improvement of S/N ratio by the signal processing. The results of the experiments also indicated that the radar could achieve high range resolution with narrowband receiver.
