Passive coherent location matched filter alternative

This paper introduces an alternative method to traditional matched filtering for PCL applications. The developed method adapts the filter structure rather than the underlying signal of the surveillance channel. This allows for minimization of interference or noise present in the surveillance channel that are correlated or uncorrelated with the reference channel. The difference between the current matched filter and the traditional approach is that idealized correlation peak for the signal is used to update the filter weights in the error chain. The method shows improvement over traditional matched filtering.
