说明：  假定均匀线列阵的阵元数为16。入射平面波为是频率为62.5Hz的正弦信号。阵元间距为波长的1/2。系统采样频率为1kHz，观测时间为0.4s，阵列加权方式为均匀加权，分别给出： (a)当平面波信号分别从0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100度方向入射时，主瓣指向90度方向的波束形成器的输出序列。
(It is assumed that the number of elements of uniform linear array is 16.The incident plane wave is a sinusoidal signal with a frequency of 62.5Hz. The element spacing is 1/2 of the wavelength. The sampling frequency of the system is 1 kHz.The sampling frequency of the system is 1 kHz, the observation time is 0.4 s, and the array weighting mode is uniform weighting.)
