Adaptive Clutter Filtering Using Autogressive Spectral Estimation
Duane E. Bowyer, Periagaram K. Rajasekaran, W.W. Gebhart · IEEE Transactions on Aerospace and Electronic Systems · 1979
A new adaptive filter to reject clutter is derived using autoregressive spectral analysis techniques. The adaptive filter performs open. Ioop processing, resulting in a shorter transient response, and is therefore suitable for radar waveforms containing only a small number of samples. A number of examples including application to ballistic missile defense are presented to demonstrate the performance capabilities of the new adaptive filter.
