A Weather Radar Ground Clutter Suppression Method Using Adaptive Coherent Pulse Integration
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingGround clutter poses a significant challenge to the accuracy of weather radar products, especially for aeroecology monitoring. Operational weather radar commonly employs a fixed coherent pulse integration (CPI) for clutter suppression.

EFFECT OF NON GAUSSIAN WEATHER CLUTTER ON PERFORMANCE OF CLUTTER-SUPPRESSION FILTERS
International Conference on Aerospace Sciences and Aviation Technology, 1985 In this paper it is investigated the performance of clutter suppression filters in non Gaussian clutter. The model chosen is Log-normal clutter and the filters considered are the optimum MTI filter and the linear prediction error filter. The performance of both types of filters in Gaussian clutter as expressed by the improvement factor (I.F) is ...
