Abstract: A passive thermal imaging system includes multiple detector arrays, imaging optics, and processing electronics. Each of the detector arrays include pixels and detect thermal electromagnetic radiation (EMR) within a band around a desired EMR wavelength. The imaging optics receive thermal EMR within the band from an object and image the received thermal EMR from a same region of the object onto pixels of each of the detector arrays. The processing electronics receive a detected signal from each of the pixels of the detector arrays, calculate a correlation value based on a multi-correlation of the received detected signals of corresponding pixels of different detector arrays, and compare the correlation value with a threshold correlation value to determine that a detection event has occurred in response to the correlation value exceeding the threshold correlation value, the threshold correlation value being equal to or between 0.8 and 0.85.
