Radar performance studies of adaptive lattice clutter-suppression filters

The paper describes the use of a prediction-error filter (realized in the form of an adapative lattice filter) for enhancing the detection of a moving target (for example, aircraft and migrating flocks of birds) in the presence of clutter. This process is well suited for use in a surveillance radar environment (for example, air-traffic control). The clutter may arise owing to reflections from ground and weather disturbances. Experimental results are included in the paper, comparing the performance of the processor with that of a conventional moving-target indication (MTI) filter.
