An infrared signal processor is provided wherein infrared energy from objects on an area of the ground is directed towards a plurality of detectors disposed in a missile. The plurality of detectors scan the area of the ground and electrical signals produced by the detectors in response to the sensed infrared energy are processed to detect the presence of a ground target, typically a tank. Potential targets are detected, that is, are distinguished from ground clutter, by determining whether electrical pulses produced by the detectors in response to the sensed infrared energy have a proper pulse duration which is consistent with the width of a tank target. In particular, the electrical pulses are passed through a bandpass filter to filter signals produced by both ground clutter infrared energy and noise.
