CFAR detector using GIS information

In order to realize the constant false alarm ratio (CFAR) processing, the adaptive threshold should be used in radar signal detection. The threshold of the CFAR detector can be calculated using the clutter of range bins nearby the cell under test. In the real world, the clutter environments is always non homogeneous, which result in the performance degradation of the CFAR detector. In this paper, the CFAR detector using geographic information system (GIS) is proposed. With the knowledge of the clutter environment, the performance of the CFAR detector can be improved remarkably. The IPIX radar data are used to validate that the CFAR detector using GIS information is outperform the other conventional CFAR detectors.
