Statistics Of The Scattering Cross Section Of A Collection Of Constant Amplitude Scatterers With Random Phase, Jihad S. Daba, Mark R. Bell
Department of Electrical and Computer Engineering Technical Reports
Complex radar targets are often modeled as a number of individual scattering elements randomly distributed throughout the spatial region containing the target. While it is known that as the number of scatterers grows large, the distribution of the scattered signal power or intensity is asymptotically exponential, this is not true for a small number of scatterers. We study the statistics of measured power or intensity, and hence scattering cross section, resulting from a small number of constant amplitude scatterers, each having a random phase. We first derive closed form expressions for the pdf of the scattered signal inte.nsity, and then …

Implementing A Hidden Markov Model With Duration Modeling On The Maspar Mp-1, C. D. Mitchell, L. H. Jamieson, M. P. Harper, R. A. Helzerman

Department of Electrical and Computer Engineering Technical Reports
This paper describes the parallel implementation of a Hidden Markov Model (HMM) for spoken language recognition on the MasPar MP-1. A major drawback of using HMMs for speech recognition is the amount of processing time required to develop and test the model. By exploiting the massive parallelism of explicit duration HMMs, we can develop more complex models for real-time speech recognition. Implementational issues such as choice of data structures, method of communication, and utilization of parallel computation functions will be explored. The results of our experiments show that the parallelism in HMMs can be effectively exploited by the MP-1. Training …

Efficient Beamspace Eigen-Based Direction Of Arrival Estimation Schemes, Gregory M. Kautz, Michael D. Zoltowski
Department of Electrical and Computer Engineering Technical Reports
The Multiple SIgnal Classification (MUSIC) algorithm developed in the late 70's was the first vector subspace approach used to accurately determine the arrival angles of signal wavefronts impinging upon an array of sensors. As facilitated by the geometry associated with the common uniform linear array of sensors, a root-based formulation was developed to replace the computationally intensive spectral search process and was found to offer an enhanced resolution capability in the presence of two closely-spaced signals. Operation in beamspace, where sectors of space are individually probed via a pre-processor operating on the sensor data, was found to offer both a …

Solutions For Bayesian Markov Random Field Estimation Problems, Chi-Hsin Wu, Peter C. Doerschuk
Department of Electrical and Computer Engineering Technical Reports
In recent years, the use of Bayesian techniques and Markov random field (MRF) models for computer vision problems has been investigated by many researchers. The major disadvantage of discrete-state MRF models is that optimal estimators require excessive and typically random amounts of computation. In this thesis, we have developed and implemented two classes of deterministic and parallelizable approximation techniques for solving Bayesian estimation problems including image restoration and reconstruction and spatial pattern classification all based on MRF models of the underlying image. The first class of approximation technique is a family of approximations, denoted "cluster approximations," for the computation of …
