Clutter suppression by means of digital MTI as applied to precision approach radar
Abstract
A major concern in the design of X-Band precision approach radars is the detection and tracking of aircraft in heavy rain clutter. The objective of the investigation was to explore the ability of a particular digital band-pass filter to discriminate Doppler shifted aircraft from such clutter. The filter was designed and tested in software using complementary PRFs. Rain clutter was modeled statistically using realistic parameters.
