TARGET DETECTION DEVICE Russian patent published in 1999 - IPC

Abstract RU 2131133 C1

FIELD: target detection. SUBSTANCE: device has two infrared radiation detectors 8, 9 as minimum. Technical result of invention lies in reduction of number of false alarms with the aid of these detectors by comparison of matrixes of images generated in sequence during one revolution on basis of preliminary alarms generated by circuits of isolation of point targets 18, 19 in matrixes of images. Difference between these matrixes generated in sequence is formed by means of difference of spectral characteristics, polarizations and parallax. EFFECT: reduced number of false alarms. 11 cl, 3 dwg
