The latest development of high resolution imaging for forward looking SAR with multiple receiving antennas

The paper provides some new developments based on the azimuth synthetic and compressing method to achieve a high azimuth resolution and unambiguous image for forward-looking SAR (F-SAR) with multiple receiving antennas. The first point of the new development is addressed on how to select and optimize the reference functions for azimuth compression. The second new point is addressed on how to configure the parameters such as wavelength and the distances between the receiving antennas. And the effect of these parameters to the practical implementation of F-SAR system will be also discussed. The third point is addressed on the methods to fuse the data from different receiving antennas for solving the left/right azimuth ambiguity.
