A new parallel algorithm for signal processing and a parallel systolic architecture of a robust constant false alarm rate (CFAR) processor with post-detection integration and adaptive censoring (RACPI) is presented in the paper. This detector is effective in conditions of flow from strong impulse interference. The ACPI CFAR processor uses sorting and censoring algorithms. We offer the sorting a...

Blood glucose management systems are an important class of Medical Cyber-Physical Systems that provide vital everyday decision support service to diabetics. An artificial pancreas, which integrates a continuous glucose monitor, a wearable insulin pump, and control algorithms running on embedded computing devices, can significantly improve the quality of life for millions of Type 1 diabetics. A ...

Title of Document: PHYSICS-BASED DETECTION OF SUBPIXEL TARGETS IN HYPERSPECTRAL IMAGERY Joshua Bret Broadwater Doctor of Philosophy, 2007 Directed By: Professor Ramalingam Chellappa Department of Electrical and Computer Engineering Hyperspectral imagery provides the ability to detect targets that are smaller than the size of a pixel. They provide this ability by measuring the reflection and abs...

In this report we describe our analysis of the influence of sea clutter non stationarity on the clutter covariance matrix estimation and its impact on the CFAR property of the normalized adaptive matched filter (NAMF). Three estimators have been considered in the analysis, i.e. the sample covariance matrix (SCM), the normalized sample covariance matrix (NSCM), and the fixed point (PF) estimator...

Polarization diversity in radar is useful to detect targets, particularly when Doppler discrimination is not possible. We introduce a new polarimetric radar model that includes the realistic dependence of the clutter reflections on the transmitted signal. We then develop a statistical polarimetric detection test, robust to heavy inhomogeneous clutter. We prove that the detector’s false-alarm ra...

This paper presents a new power-line disturbance detection algorithm. The utilized recursive least square (RLS) prediction error lter extracts the power-line disturbance signal from recorded data, and the modi ed stop-and-go cell average constant false alarm rate (CA CFAR) detector makes a decision based on the squared output of the previous stage. The detection performance of the proposed algo...

We present a modified version of the polarimetric whitening filter (PWF) for target detection in single-look complex images captured by polarimetric synthetic aperture radar (PolSAR). The modified version enables the derivation of the sampling distribution of the PWF under several product model distributions for the polarimetric scattering vector. Specificly, a constant false alarm rate (CFAR) ...
