Research on Multi-Domain Dimensionality Reduction Joint Adaptive Processing Method for Range Ambiguous Clutter of FDA-Phase-MIMO Space-Based Early Warning Radar

open access: yesRemote Sensing, 2022
The ground and sea clutter received by space-based early warning radar (SBEWR) has severely range ambiguous characteristics due to its platform location, and the non-stationary factor caused by Earth’s rotation makes the received clutter at different ...

Efficient Methods of Clutter Suppression for Coexisting Land and Weather Clutter Systems [PDF]

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2009
The removal of coexisting land and weather clutter signals is a common problem in many radar applications. Although the optimal method for land-weather clutter suppression is known, it is usually not amenable to implementation due to computation and storage limitations of the processor.

Eigen-based clutter filters for color flow imaging: Single-ensemble vs. multi-ensemble approaches [PDF]

open access: yes, 2007
In designing eigen-based clutter filters for color flow imaging, one of the challenges is to develop an accurate way of estimating the eigen-components that represent clutter in slow-time ensembles.

Robust knowledge-aided sparse recovery STAP method for non-homogeneity clutter suppression

open access: yesThe Journal of Engineering, 2019
Conventional space–time adaptive processing (STAP) methods would suffer severely performance loss in the complex clutter environment of an airborne-phased array radar, especially when the estimated clutter covariance matrix (CCM) is corrupted by the ...

Distribution Characteristics of Ground Echo Amplitude and Recognition of Signal Grazing Angle

open access: yesSensors, 2021
With the continuous advancement of electronic technology, terahertz technology has gradually been applied on radar. Since short wavelength causes severe ground clutter, this paper studies the amplitude distribution statistical characteristics of the ...

Doppler polarimetric ground clutter identification and suppression for atmospheric radars based on co-polar correlation

open access: yesJournal of Telecommunications and Information Technology, 2001
A new clutter suppression technique that uses both Doppler and polarimetric information is presented. Polarimetric properties of the target and clutter are calculated per Doppler frequency cell and based on this information clutter suppression is ...

Fast-time STAP performance in pre and post range processing adaption as applied to multichannel SAR [PDF]

open access: yes, 2006
Hot-clutter cancellation using fast-time Space Time Adaptive Processing (STAP) can occur either pre or post range processing (RP) and to date, there has not been a direct comparison on which method offers the best results. This paper provides an analytic

Ground clutter suppression method based on FNN for dual-polarisation weather radar

open access: yesThe Journal of Engineering, 2019
Conventional clutter suppression methods in the field of precipitation detection generally use fixed parameters, resulting in poor clutter suppression in complex weather conditions and regional environments.
