The semi-active laser (SAL) last pulse logic seeker utilizing a focal plane array is obtained by combining the semi-active laser last pulse logic sal processing using a single PIN photodiode with a staring imaging infrared (I.sup.2 R) focal plane array detector, such as InSb. The result is an improvement that renders the seeker capable of operating in three different modes: SAL only, I.sup.2 R only or simultaneous multi-spectral processing in SAL/I.sup.2 R. The improvement uses a single PIN photodiode detector with an imaging infrared focal plane array (...


[ We claim:] [1.] In a seeker for locating and tracking a target in a scene by detecting and processing laser pulses reflected by the target in the scene, the seeker having semi-active laser last pulse logic circuit for determining the last pulse indicative of the true target, the circuit containing a pulse discriminator for setting a pulse detection threshold, the threshold decaying at a given constant rate, and for producing pulse presence signals in response to the detected laser pulses and a microprocessor capable of receiving and processing the puls...
