Abstract : This final technical report describes the work accomplished on the Track-While-Scan Data Processing Investigation Contract. The objective of this program was to demonstrate the feasibility of using simple microelectronic shift register circuitry to inhibit detections that do not satisfy appropriate scan-to-scan correlation criteria. In the absence of such rejection circuitry, the TWS digital computer is required to sort and reject frequent noise detections and this substantially influences the size of computer required. The program entailed the fabrication of noise rejection circuitry and its evaluation in conjunction with the breadboard infrared Track-While-Scan subsystem developed under an earlier contract. The results of the evaluation tests have verified the performance characteristics of the noise rejection circuitry when tracking simulated and moving targets, and have demonstrated that implementation of the noise rejection circuitry can be accomplished with low-cost low-weight microelectronic modules. The performance gain resulting from the inclusion of the noise rejection circuitry in a typical infrared track-while-scan sensor is shown to correspond to either (1) a 68% easing of the computer load or (2) a 15% improvement in detection sensitivity.
