| Abstract: | In this paper, we analyze the methods of estimating DOA (direction of arrival) of target signals, then propose that it is available for using the digital beam forming technique in the projectile system. Aimed at the problem of low signalnoise ratio, a modified method is given by substituting cycle cross correlation matrix for cross corelation one. Montecalo trials demonstrate that this method has superior performance of noise suppression. |
