图像的滤波，可以适用于人民币序列号的识别相关步骤-Image filtering can be applied to the yuan serial number to identify the relevant steps

EKF扩展kalman滤波估计二维平面运动轨迹，实现二维平面有源雷达对目标距离和速度的跟踪。-Kalman filtering estimation of 2D motion trajectory EKF extension, realize the planar active radar for target distance and velocity tracking.

假设目标是一维，采用CV模型，用kalman滤波方式进行滤波，验证目标跟踪的有效性。-Assume that the target is one dimension, using the CV model, is filtered by the Kalman filtering method, validate the target tracking.
