some code for radar system simulation

偏振控制器，利用绑架球算法对QHQ型进行方位角的误差分析(Polarization controller, using the kidnapping of QHQ type ball algorithm for the azimuth error analysis)

extracts window coordinates from an image of a building. window pictures must be taken at a straight angle, and the picture needs to be shot at daylight.

this program simulates 1D electromagnetic Maxwell equations with absorbing boundary condition to prevent reflection from the boundaries of the problem space. this is by using finite difference time domain method FDTD
