ABSTRACT:
A scanning sensor system scans a detector array across a field of view, the array comprising a plurality of infrared detector elements which are positioned in the array with spaces interspersed therebetween. The system scans separate detector elements across separate portions of the field of view at a slow scan rate and then rapidly steps to scan a different portion of the field of view, thereby permitting a high frame rate despite a low target sensing scan rate to lower the required total sample rate, reduce processing circuit complexity, and reduce the number of required interconnections between the focal plane array and on-gimbal processing circuitry.
