The Semi-Active Laser (SAL)/Infrared Imaging (I2R) Seeker concept consists of utilizing a small single Silicon PIN Photodiode detector in conjunction with a staring midwave infrared focal plane array (FPA) and correlating the temporal laser returns obtained from the PIN detector with the spatial laser returns obtained from the FPA. The correlation of the spatial-temporal returns will allow identification of the correct laser return on the FPA. Once the correct laser return is identified, the seeker can position a track gate about the designated target identified by the correct laser return and generate guidance commands to guide a missile to a target. The concept will enable SAL, I2R, or SAL/I2R (simultaneous) processing to be accomplished. Guidance commands will be generated with the FPA detector only, using the multispectral data.
