Computer modelling of ground clutter in airborne radar
IEE Colloquium on Radar System Modelling, 1998The modelling of ground clutter in airborne radar systems is an essential component of assessing system performance but is computationally intensive because of the requirement to consider ground returns over the full extent, or at least a substantial portion, of the Earth's surface which is visible to the radar platform. This paper describes a computer

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 ...

Study on Clutter Suppression on Ground Penetration Radar
2018 IEEE International Workshop on Electromagnetics:Applications and Student Innovation Competition (iWEM), 2018When the antenna of the underground radar is away from the ground surface, large reflection occurs on the ground surface, and it is difficult to extract weak responses in the ground and to reconstruct an image. In this paper, clutter removal means for suppressing reflection by the ground surface was studied, assuming application in landmine exploration

Separating Ground-Moving Targets from Clutter
1998In this chapter, after briefly examining the problem, we will be introduced to two highly effective techniques for detecting such targets. One is called Classical DPCA, for displaced phase center antenna. The other and newer technique are called notching or clutter nulling. We'll take up Classical DPCA first; then, notching; and, finally, a combination

VHF airborne passive bistatic radar ground clutter investigation
IET International Conference on Radar Systems (Radar 2012), 2012Airborne passive bistatic radar is currently experiencing renewed interest for both air-to-air and air-to-ground operation. An experimental airborne passive bistatic radar demonstrator system, that uses FM broadcast transmissions as an illuminator of opportunity, has been designed and constructed and flown on airborne experiments to collect data.

Nonlinear spectral-estimation methods for ground clutter analysis
Electronics & Communication Engineering Journal, 1989A simple ground clutter model has been analysed using nonlinear methods of power spectral estimation and the performance of these methods has been studied. The methods considered are the maximum entropy method (MEM), the maximum likelihood method (MLM), the leastsquares method (LSM), the autoregressive moving average(ARMA) method and Prony's energy ...

The Record of the 1993 IEEE National Radar Conference, 2002
The exploitation of coherent records from a low-resolution dual-polarization S-band radar gives more insight into the polarimetric behavior of ground clutter, thus leading to a better assessment of polarimetric and frequential techniques as applied to ground clutter rejection. Stationary and polarization features of fixed echoes and spread clutters are

Ground surface scattering and clutter suppression in ground-penetrating radar applications
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012A scattering and imaging, clutter characterization and suppression study is carried out to demonstrate the feasibility of sensing buried targets in a terrain environment with a rough ground surface. The investigation is pertinent to detection performance analysis and prediction for a vehicle-based, ultra-wideband, ground-penetrating radar system.
