Estimating the term…
A surface wave radar system including a receive antenna array (20, 22) for generating receive signals, and a data processing system (24) for processing received data representing the receive signals to mitigate ionospheric clutter. The received data is range and Doppler processed, and a spatial adaptive filter (52) is trained using training data selected from the processed data. The training data includes ionospheric clutter data and excludes cells which contain target data and substantial sea clutter. The processed data is filtered using the filter (52), which may be based on loaded sample matrix inversion. The antenna array (20,22) may be two-dimensional having an L or T shape.
A surface wave radar system including:
A surface wave radar system as claimed in claim 11, wherein said array includes a one dimensional broadside array of vertically polarised doublets, said broadside array being substantially perpendicular to a receiving direction of said antenna, and each of said doublets being substantially parallel to said receiving direction.
A surface wave radar system having a two-dimensional receive antenna array.
A method for processing range and Doppler processed data in a surface wave radar receiver, including, for each range, the steps of:
A data processing system for processing received surface wave radar data to mitigate ionospheric clutter.
