Comparison of Doppler clutter cancellation techniques for naval multi-function radars

摘要

The authors describe a comparison of fixed and adaptive clutter cancellation processes applied to measured multi-function radar (MFR) data in a littoral environment. The adaptive filters require estimates of the clutter covariance, and comparisons of different strategies for obtaining this are made. The results for the adaptive filters generally show substantially improved target dctectabilities over non-adaptive filters.
