直角坐标系下的单雷达kalman滤波，实现直角坐标系下单部雷达对目标的跟踪。-The single radar Kalman filter in Cartesian coordinates in the Cartesian coordinate system, place an order of radar target tracking.

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.
