And the paper achieved conversion from the completed polar coordinates to rectangular coordinate, and solved two key problems, dead address and blind zone phenomenon.
本文完成了雷达数据从极坐标到直角坐标的转换,解决了坐标转换易出现的死地址和盲区现象。
The CORDIC algorithm is adapted to convert the polar coordinate image to the rectangular coordinate image, while cubic spline interpolation is used to interpolate the vacant pixels.
本文采用数字坐标旋转(CORDIC)算法将极坐标图像转化为直角坐标图像,并采用三次样条插值的方法对漏点进行弥补。
