Abstract (en)
[origin: EP0306391A1] The apparatus which can be used on ammunition for attacking a thermal-engine vehicle comprises a detector with a low angular field having a sensor (24) sensitive in the range from 3 to 5 mu m and a sensor (34) sensitive to near-infrared; means for sampling the output of the sensors at such a rate that there is an overlap of the zones corresponding to successive samples; means for storing a predetermined number of successive samples; calculation means forming the difference between the samples of the response of the first sensor and the average of n preceding samples and, in the event that a threshold is exceeded, causing the search for an end of transition by comparison between stored successive samples and a comparison between the samples of the signal supplied by the second sensor for the transitional zone with specific minimum and maximum values. <IMAGE>
