Abstract:
1. A system comprising an infrared sensor; and a processor programmed to process multiple frames of image data captured by the sensor, wherein the processor is programmed to estimate a centroid of a blur spot target in each of the frames; and separately estimate radiometric amplitude of the blur spot target in each of the frames according to an expression where A1(X1,Y1,f) is the radiometric amplitude, X1 and Y1 are subpixel estimates of the centroid, F1x and F1y are a point spread function in row and column pixels, vectordata is the image data in i and j sensor coordinates, bed indicates that pixels are summed over a region in the image data, and f denotes the multiple frames that are statistically analyzed to produce mean and standard deviation for the amplitude and coordinates.
