Abstract
Apparatus and associated methods relate to a seeker for a Semi-Active Laser (SAL) guided missile. The seeker has a Short-Wave InfraRed (SWIR) camera and a Pulse Timing Logic (PTL) detector. The PTL detector has a SWIR photo detector axially aligned with a lens stack of the SWIR camera. The SWIR photo detector is configured to detect a sequence of SWIR pulses generated by a SAL target designator and reflected by a designated target. The PTL detector has a pulse timer configured to identify a sequence pattern of the detected sequence of SWIR pulses, and to predict a timing of a next SWIR pulse in the identified sequence pattern so as to synchronize exposure of the SWIR camera to capture a next image of the designated target at the predicted timing of the next SWIR pulse. Such exposure timing can advantageously improve the signal to noise ratio of the next image.
