【Abstract】 An optimum spatial filter (OSF) is implemented on a cylindrical array based on the mathematical expression. Detection of weak signal and suppression of interference are studied in case of multiple interferences in the neighborhood. The analysis shows that the OSF can effectively suppress multiple interferences and extract weak signals. The OSF can conveniently be implemented on a cylindrical array of digital sonar.更多还原
