Timing Analysis and Ambiguity Performance of Multistatic SAR

Abstract:
Multistatic SAR systems enable significant benefits such as tomographic imaging and 3D surface deformation estimation at the expenses of system complexity. Multistatic SAR requires a more complicated timing analysis than monostatic SAR since multiple platforms are transmitting and/or receiving, usually in the same cycle. The nadir-return and ambiguity analyses also become more challenging due to existence of multiple pulses-in-air from different platforms, direct path leakages, and non-zero bistatic angles. Therefore, it is critical to develop a unique timing and ambiguity analysis tool in the early design phase of multistatic SAR systems. Here we introduce such a tool and present example results.
