| Abstract: | The traditional radar image-drawing algorithm based on real-time direct-coordinate transformation is inefficient, and is not able to solve the problem of dead address and blind spot fundamentally. In this paper, we design and implement a new drawing algorithm based on lookup-table, which has greatly improved the drawing speed and solves the problem of blind spots and die address. |
