摘　　要：通过对目标方位识别方法进行分析 ,指出在弹载探测系统中可采用数字波束形成技术实现其目标方位识别 ,针对其低信噪比问题 ,采用循环相关矩阵代替协方差矩阵 ,仿真试验表明该方法具有良好的噪声抑制特性。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.
