Comparison of Detection Performance of Selected Two-Channel Algorithms.
Abstract
Recent work on intersensor processing has stimulated interest in techniques for determining information common to two data sequences which may be used for detection, tracking or a combination of these and other functions. Three algorithms which seemed naturally to suggest themselves for intersensor processing were compared. It was determined that the use of a normalization factor significantly degrades detection performance in regions characterized by low time-bandwidth product TW < or = 64. For TW > or = 120, all three algorithms performed about equally on the detection function. The principal implication of this work is that the operating mode of the system (which may dictate the low time-bandwidth product used) may affect the choice of algorithms to be used. In a tactical application where decisions must be made quickly, use of an unnormalized correlator may be mandatory. In a situation where long integration times are acceptable, a normalized formula such as the coherence detector may be chosen for data processing, as opposed to signal processing, economies. (Author)
