说明：  等间距线性阵列，阵元数M=8，阵元间距d= λ /2，目标方位φr =0°，无噪 分别仿真计算等幅加权、汉宁窗加权、切比雪夫加权时的阵列方向图，定性分析产生的原因。（可分析不同窗函数引起的主瓣、旁瓣影响）
(Equally spaced linear array, the number of array elements M = element spacing d = λ/2, target azimuth φr = 0, no noise respectively simulation amplitude weighted Hanning window weighted cut than snow laid upon the right of the array direction diagram, the qualitative analysis of the causes. (May analyze different window function causes the main lobe, side lobe effects))
