Abstract:
A multispectral imaging system identifies disturbed ground regions in an interrogation area and includes an image sensor. The image sensor includes a photodetector array, a filter that transmits a non-near infrared (non-NIR) reference band and NIR including band from diffusely scattered light to the photodetector array. The 2-D photodetector array generates separately detected first non-NIR reference band data and NIR comprising band data. A processor for data processing is coupled to the photodetector array to receive the non-NIR reference band data and NIR band data. The data processing includes utilizing both the NIR band data and the non-NIR reference band data to generate processed image data that can be used to identify disturbed ground regions within the interrogation region.
