Estimation of motion parameters from image sequences
(Monterey, California. Naval Postgraduate School, 1991-06)
The image motion analysis algorithms that generate the two dimensional velocity of objects in a sequence of images are developed. The algorithms considered consist of: the parallel extended Kalman filter method; the ...
Hybrid hard and soft decision decoding of Reed-Solomon codes for M-ARY frequency-shift keying
(Monterey, California. Naval Postgraduate School, 2010-06)
All modern communication systems use some form of forward error correction coding. Generally, coding gain is improved when soft decision decoding is used instead of hard decision decoding. While soft decision decoding is ...
The effect of autopilot configuration on missile response.
(Monterey, California. Naval Postgraduate School, 1989-03)
The U.S. Army Defense Ammunition Center and School (USA DACS), Evaluation Division (SMCAC-DEV), has been tasked by the U.S. Army Armament Research, Development and Engineering Center (ARDEC), Rock Island, IL, to test ...
Reed-Muller codes in error correction in wireless adhoc networks
(Monterey California. Naval Postgraduate School, 2004-03)
The IEEE 802.11a standard uses a coded orthogonal frequency division multi-plexing (COFDM) scheme in the 5-GHz band to support data rates up to 54 Mbps. The COFDM was chosen because of its robustness to multipath fading ...
Fusion of ground-based sensors for optimal tracking of military targets
(Monterey, California. Naval Postgraduate School, 1989-12)
Extended Kalman filtering is applied as an extension of the Position Location Reporting System (PLRS) to track a moving target in the XY plane. The application uses four sets of observables which correspond to inputs from ...
Angular rate estimation by multiplicative Kalman filtering techniques
(Monterey, California. Naval Postgraduate School, 2003-12)
Spacecraft attitude estimation and pointing accuracy have always been limited by imperfect sensors. The rate gyroscope is one of the most critical instruments used in spacecraft attitude estimation and unfortunately ...
Optimal linear quadratic Gaussian controller design for a flexible spacecraft simulator
(Monterey, California. Naval Postgraduate School, 1995-12)
The experimental verification of active control methods for vibration suppression of large flexible structures in space is essential for precision optical and military payload operations. The Flexible-Spacecraft Simulator ...
Back-propagation neural networks in adaptive control of unknown nonlinear systems
(Monterey, California. Naval Postgraduate School, 1991-12)
The objective of this research is to develop a Back-propagation Neural Network (BNN) to control certain classes of unknown nonlinear systems and explore the network's capabilities. The structure of the Direct Model Reference ...
Wavefront reconstruction and mirror surface optimization for adaptive optics
(Monterey, California: Naval Postgraduate School, 2014-06)
The problem of wavefront reconstruction is important in high precision optical systems, such as astronomical telescopes, where it is used to estimate the distortion of the collected light caused by the atmosphere and ...
Detection of a low power communication signal in the presence of a strong co-channel TV broadcast interference using Kalman filter
(Monterey, California: Naval Postgraduate School, 2014-12)
This research focuses on the detection of a low power communication signal in the presence of a strong co-channel television broadcast interference signal. The presence of strong co-channel interference makes the recovery ...
