1. A method for signature matching, the method comprising: receiving, via one or more processors, a first target profile associated with a first data signal, the first data signal associated with a first target object; receiving, via the one or more processors, a second target profile associated with a second data signal, the second data signal associated with the first target object or a second target object; generating, via the one or more processors, a comparison distance utilizing a comparison distance function and based on a comparison of one or more data points associated with the first target profile and one or more data points associated with the second target profile; determining, via the one or more processors, a signature matching score based on the comparison distance, wherein determining the signature matching score further comprises: generating a ratio based on the comparison distance, selecting a likelihood ratio based on the ratio determined from the comparison distance, wherein the likelihood ratio associated with a match probability density function and a mis-match probability density function, and wherein the determining the signature matching score based on the comparison distance further comprising determining the signature matching score based on the comparison distance and the selected likelihood ratio.
