WebThe standard analysis of Barker-coded incoherent scatter experiments is based on a matched ﬁlter with an im- pulse response which is a mirror image of the code itself. The method produces small sidelobes which cause contamination from regions outside the nominal range gate. http://rsss.ece.illinois.edu/sites/rsss.ece.illinois.edu/files/B3cscatter%20copy.pdf
