Cross Beam STAP for Nonstationary Clutter Suppression in Airborne Radar

International Journal of Antennas and Propagation, 2013
A novel space-time adaptive processing (STAP) method for nonstationary clutter suppression is proposed. The developed method forms a multibeam along the cross line to participate in adaptive processing, which sufficiently utilizes the spatial information

A Weather Radar Ground Clutter Suppression Method Using Adaptive Coherent Pulse Integration

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Ground 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.

A Novel Main-Lobe Cancellation Method Based on a Single Notch Space Filter and Optimized Correlation Analysis Strategy

International Journal of Antennas and Propagation, 2019
The high-frequency hybrid sky-surface wave radar (HFSSWR) is a new kind of over-the-horizon radar system. Combining the advantages of both the sky wave radar and the surface wave radar, HFSSWR has drawn much attention in recent years.
