Theory and implementation evaluation to the STAP/ADAPT diversity programme
… Office implemented one such programme: the STAP/ADAPT programme, which is the focus of this evaluation. The evaluation consisted of two parts, namely: a theory and an implementation evaluation.

Robust GM Wiener Filter in the Complex Domain
… points from a dataset. Since the early 1970s, STAP has been used in radar systems for their ability to "filter clutter, interference and jamming signals. One major flaw with early STAP radar systems is the reliance on non-robust estimators to estimate the noise condition. When even a single …

Improved broadband adaptive beamformer performance
… of time-taps in space-time adaptive processors (STAP) as a method of increasing the number of interferers the beamformer can simultaneously cancel in an environment containing a mix of narrowband, partialband and broadband interference is studied. An alternative scheme to free up degrees of …

Secure Time-Aware Provenance for Distributed Systems
… we present Secure Time-Aware Provenance (STAP), a novel approach that provides the fundamental functionality required to answer such forensic questions -- the capability to "explain" the existence (or change) of a certain distributed system state at a given time in a potentially …

Robust Steering Vector Mismatch Techniques for Reduced Rank Adaptive Array Signal Processing
… airborne radar space-time adaptive processing (STAP) and steering vector mismatch robustness. This is an important area of research in the field of airborne radar signal processing since practical STAP algorithms should be robust against various kinds of mismatch errors. The clutter return in an …

Robust Adaptive Signal Processors
… and measured Space-Time Adaptive Processing (STAP) airborne radar data are used to show performance enhancements. The STAP application area is described in detail in order to further motivate research into robust adaptive processing.

Sparsity based methods for target localization in multi-sensor radar
… problem two sparsity-based algorithms, the MP-STAP and the MBMP-STAP algorithms are proposed that utilizes knowledge of the upper bound on the number of targets. A constant false alarm rate (CFAR) sparsity based detector that does not utilize any information on the number of targets referred to …

Cramer-Rao Lower Bound Derivation and Performance Analysis for Space-Based SAR SMTI
… model is used in space-time adaptive processing (STAP) approaches for SMTI. A statistical model of the received signal is formed using the derived deterministic target signal, and gaus- sion distributions for noise and clutter. CRLBs for the statistical model and target parameters are derived by …

Sensorloze detectie en regeling van de lasthoek bij hybride stappenmotoren
Stappenmotoren zijn de machines bij uitstek om positioneertaken uit te voeren bij laag vermogen. Na elke stuurpuls zal de drive de stappenmotor zodanig aansturen dat de rotor een vaste hoekverdraaiing uitvoert. Door het tellen van het aantal stuurpulsen is positioneren in openlus mogelijk. Wanneer …
