在测试雷达时,往往需要测试雷达的数据是否准确,这时就需要在雷达图中显示一条标准的直线作为对比。
"create a wall" import numpy as np import matplotlib.pyplot as plt import sys def main(distance): theta = np.arange(-45 / 180 * np.pi, 45 / 180 * np.pi, 1 / 180 * np.pi) tmp = np.cos(theta) wall = distance / tmp with open("dis.csv",mode = ‘w‘) as file: counter = 0 s = ‘‘ for n in wall: s += str("%d,"%n) counter += 1 while counter < 360: s += "0," counter += 1 file.write(s) file.close() lin = np.linspace(distance+1000,distance+1000,len(theta)) plt.polar(theta, wall) plt.polar(theta, lin) plt.show() if __name__ == "__main__": main(int(sys.argv[1]))
想生成一条3m的直线,只需要输入:
python buildwall.py 3000
即可
