Note:
1. Looking forward from the back, the left side of the radar is the negative axis
of X-axis, the right side is the positive axis of X-axis;the front side of the radar
is the positive axis of Y-axis, and the far away from the radar is the positive
velocity, while close to the radar is the negative velocity.
2. Cartesian coordinate system is used for point cloud, target track and
clustering cloud, and polar coordinates are used for tracking output.
