Abstract(in English) Foreign Object Debris (FOD) on the airport runway are possible to be serious risk for aircrafts. Detection system by using radar is being developed. For small object detections, it is important to obtain high S/C (Signal to Clutter) ratio. Authors have proposed an interference wave suppression method for automotive radar by using projection transform. It is considered to be effective for small object detection. FMCW radar modulation has been generally adopted for FOD detection on the airport runway. In the beat frequency of FMCW, interference signals such as from moving objects outside the runway contaminates the environment signal (reference signal) that is used to estimate P matrix for clutter suppression. On the other hand, the stepped multiple frequency pulse modulation proposed by the authors has a pulse Doppler filter (PDF), which enable us to avoid interference of signals from moving objects. That is why the proposed modulation is considered to be suit to the projection transform to suppress the clutter signals. In this article, stepped multiple frequency CPC is adopted as the radar modulation. The field experiment results are conducted to verify the proposed method for FOD detections.
