Zusammenfassung: | PURPOSE:To reduce satisfactorily the probability of a wrong alarm and to increase the distance for detection of a target by obtaining the target detection data containing no noise from the picture data obtained by receiving the infrared rays radiated from the target. CONSTITUTION:A picture processor 16 supplies the data given from a binary picture memory 15 to an addition part 161. The part 161 adds for each frame the data on each data given from the memory 15 in response to the change of the oscillating angle of an imager 11 and stores the added data successively to a frame memory 162 in the form of the integration value. This data undergoes a filtering operation through a filtering operation part 164, and the result of this filtering result is supplied to a detection decision operation part 165. The part 165 compares the supplied filtering result with the threshold value to decide a target. |
