The advantage and disadvantage of the method of azimuth pre-filtering and undersampling and the method of subaperture processing are compared.
比较了方位向预滤波降采样方法与子孔径处理方法各自的优缺点。

We introduce an algorithm to detect the undersampling patch in the input data and to avoid appearance of the wrong connected triangles around the boundary.
Tracing failure and undersampling are frequently emerged when the two dimensional tracing and measurement function of commercial Coordinate Measuring Machine software is applied.
