| 摘要 |
The invention relates to an infrared sensor incorporating at least one detector (8, 9) by means of which the number of false alarms can be reduced by comparing image matrices successively generated in one revolution on the basis of prealarms generated in the image matrices by point target extractors (18, 19). Between these matrices generated in succession, differences are introduced by means of a different spectral response, polarization selection and parallax.
