相控阵直角坐标与极坐标先的方向图,可以调节字体与线条大小-Phased array Cartesian coordinates and polar coordinates before the pattern

既然要得到的是频率玫瑰图，就要求出每个方向上在这个月中出现的次数，然后除上整个月的风向次数。通过对比，发现利用极坐标比直角坐标更简便些，故利用 find（）寻找方向值，length计算方向的长度，polar绘制玫瑰图(Since you want a frequency rose diagram, ask for the number of times per month in each direction, and then count the number of winds in the w

Mathematics验证：真时延移相器改变频率不影响最大辐射角度。(Mathematics verification: true time delay phase shifter changes the frequency does not affect the maximum radiation angle.)
