Adaptive Processing With Signal Contaminated Training Samples [PDF]
We consider the adaptive beamforming or adaptive detection problem in the case of signal contaminated training samples, i.e., when the latter may contain a signal-like component. Since this results in a significant degradation of the signal to interference and noise ratio at the output of the adaptive filter, we investigate a scheme to jointly detect ...

Object Recognition in High-Resolution Indoor THz SAR Mapped Environment
Synthetic aperture radar (SAR) at the terahertz (THz) spectrum has emerging short-range applications. In comparison to the microwave spectrum, the THz spectrum is limited in propagation range but benefits from high spatial resolution.

Short-Range SAR Imaging From GHz to THz Waves
Synthetic aperture radar (SAR) is a well-known imaging technique and most commonly used up to the microwave frequency spectrum (below 30 GHz) which provides spatial resolution in the sub-m range.

Separability study of statistical features of RCS sequences extracted by sliding windows
Statistical features are commonly used in radar target recognition tasks using radar cross section as the data source. The traditional statistical feature extraction way may not make better use of the data information, making the target classification ...

A novel heuristic for the analysis of block sign LMS algorithm
This paper presents a new heuristic for the analysis of adaptive filtering algorithms. It combines Price's Theorem (which is strictly valid when the random variables are jointly Gaussian) with a probabilistic model of the input data that assumes ...

WDM monitoring technique using adaptive blind signal separation [PDF]
We present a cost-effective method of monitoring the performance of wavelength-division-multiplexed (WDM) channels. The method is based on simple optical signal processing in combination with electronic signal processing.
