FOD Detection on Airport Runway with an Adaptive CFAR Technique
Cell averaging CFAR (CA-CFAR) detection method is usually applied to homogeneous clutter background environment. However, when the background is complex or non-homogeneous, the performance of CA-CFAR may decline greatly. In this paper, focusing on the effective detection of FOD (foreign object debris) targets on airport runway, an adaptive cell averaging CFAR technique (ACA-CFAR) is used to obtain relatively good detection performance, especially when targets exist in the clutter edge or multi-targets interference environment. Experimental results show the effectiveness of the ACA-CFAR detector in the complex airport runway environment.
