Abstract
Strong sidelobes not only lead to false alarm, but also affected the target detection. By overlaying an orthogonal coding over any analog or digital signal, we can completely remove most of the ACF (auto correlation function) sidelobes without any increase to the mainlobe sidelobes. In this paper, we discuss how to choose the original signal for HFSW radar and give the affection of different overlaying matrix.
