Canonical Framework for ATI and DPCA
The topic of moving-target detection in clutter has been extensively studied, there are many methods, such as Along- Track Interfero-metric (ATI) phase, Displaced Phase Center Antenna (DPCA) method, Space-Time Adaptive Processing (STAP), or some other metrics. A canonical framework is proposed that encompasses ATI and DPCA. The statistical test metric for ATI and DPCA is established in an simple form, via the definition of the complex central Wishart distribution, deduces the statistics of the test metric, the probability distribution of the test metric for ATI and DPCA have the complex central Wishart distribution of 1×1 case, namely the χ2- distribution. The theory foundation offers the possibility to construct the united multi-channel SAR GMTI detector, and derive the constant false-alarm rate (CFAR) detector tests for separating moving targets from clutter.
