要約(英語): Authors have proposed the stepped multiple-frequency step radar modulation. The radar modulation also has been demonstrated for various applications through the verification experiments. Narrowband signals are transmitted and received in time division in the modulation. The high range resolution corresponding to the transmission bandwidth is obtained by synthesizing the received signals. That is why the radar modulation enables us achieve both a long-range performance and a high range resolution by a low hardware load. In recent years, 5GHz bandwidth has been allocated to millimeter-wave radar in 79GHz band. In addition, 8GHz bandwidth in 90GHz band tends to be allocated for detecting foreign object debris on runways in the world. In this paper, the parameter studies on the multiple-frequency step radar for the detection of small objects in background clutter environments are conducted. The parameter study results show that the stepped multiple-frequency step radar can achieve centimeter range resolution using some tens to hundreds of MHz A/D converters, which significantly mitigates the effect of the background clutter. Evaluation results indicated that the stepped multiple-frequency step radar has the potential for detecting small objects in background clutter environments.
