A Modified STAP Estimator for Superresolution of Multiple Signals

الملخص EN

A modified space-time adaptive processing (STAP) estimator is described in this paper.

The estimator combines the incremental multiparameter (IMP) algorithm and the existing beam-space preprocessing techniques yielding a computationally cheap algorithm for the superresolution of multiple signals.

It is a potential technique for the remote sensing of the ocean currents from the broadened first-order Bragg sea echo spectrum of shipborne high-frequency surface wave radar (HFSWR).

Some simulation results and real-data analysis are shown to validate the proposed algorithm.
