Abstract
We analyse the 3-dimensional point spread functions of point sources reconstructed by the backprojection algorithm for different flight paths from data from a single channel without additional information. In this scenario, SAR-algorithms normally generate two dimensional images, because of large ambiguities in height, whereby the horizontal slices are mere copies of the slice at ground level. Our investigation focuses on the effect of the flight path on these ambiguities. For this purpose, we compute the simulated 3D pointspread function for several flight paths and compare them to those for a straight flight path. We analyze the volume data through slices parallel to the coordinate planes and a topological peak detection algorithm. For the non-straight flight paths, the location of the point target can be pinpointed in the set of slices parallel to each coordinate plane, but not for the straight flight path.
