Efficient Fourier based Algorithm Development for Airborne Moving Target Indication
TNO Defensie en Veiligheid
This paper shows how the signal model that is commonly used as a starting point in multi-channel Space Time Adaptive Processing (STAP) for airborne Moving Target Indication (MTI) formally corresponds to a model that can be derived from a bi-static Synthetic Aperture Radar (SAR) model extended for multiple channels. With the help of this generalisation one arrives at an operation that can be performed on the conventional airborne MTI STAP model. The result yields an orthogonal domain that allows for a design of onedimensional clutter-rejecting algorithms. This should drastically decrease the computational demands in comparison with the high-performance two-dimensional algorithms described in the airborne MTI literature so far.
