Sparse LCMV beamformer design for suppression of ground clutter in airborne radar
IEEE Transactions on Signal Processing, 1995Cancellation of the ground clutter received at an airborne phased array radar is an inherently two dimensional problem. Clutter returns are Doppler shifted due to platform motion forcing the use of processors that can resolve targets in both velocity (Doppler) and azimuth.

Adaptive clutter suppression for ground penetrating radar
SPIE Proceedings, 2005Adaptive methods are currently in use for GPR to detect shallow-buried targets in the presence of ground-bounce that may be orders of magnitude greater than the target response. One such method that has been used with noteworthy success to reduce the soil background has been called the Principal Components Algorithm (PCA) that applies the Mahalanobis ...

Ground clutter suppression: Preliminary analysis of Qujing incoherent scatter radar
2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE), 2018Incoherent scatter radar (ISR) detects the Thomson scatter echo of free electrons to inverse ionosphere parameters and is thought as the most powerful instrument to observe the ionosphere on the ground. In fact there are usually severe ground clutters around altitude 100km in the echo data.

Joint physical and virtual STAP for strong ground clutter suppression and imaging
2018 IEEE Radar Conference (RadarConf18), 2018Clutter suppression is a mandatory step in order to detect slow moving targets embedded in strong ground clutter. Multichannel systems allow for sufficient spatial degrees of freedom to be available and as a consequence, allow for STAP processing to be applied. In recent times, a processing scheme that exploits a single channel SAR system with high PRF

IEEE Transactions on Aerospace and Electronic Systems, 2018
In a recent paper, the problem of inverse synthetic aperture radar (ISAR) imaging moving ground targets was discussed and an effective solution based on a novel joint space-time adaptive processing (STAP)-ISAR formulation was proposed. In the case of bistatic geometry, ISAR imaging can be simply and effectively enabled via the bistatically equivalent ...

Adaptive ground clutter suppression for airborne weather radar based on echoes power
IET International Radar Conference 2013, 2013Airborne weather radar is an important navigation equipment to ensure flight safety. A new adaptive clutter suppression method based on echoes power is proposed in this paper, which is for airborne weather radar operated in wind shear mode. By using the priori information and the polar coordinate centroid method, the centre frequency and bandwidth of ...

A clutter suppression method of ground penetrating radar for detecting shallow surface target
IET International Radar Conference 2015, 2015GPR for detecting shallow surface target has heavy clutter and target echo cannot be distinguished easily. This paper proposes a PCA-SVD mixed clutter suppression method to realize dimension reduction and reconstruction, which can improve the performance of clutter suppression effectively. SVD processing remove direct wave, firstly.
