Enhanced Inverse Synthetic Aperture Radar Imagery Using 2 - D Spectral Estimation
approved: _____________________________________________________ S. Lawrence Marple Jr. This research focused on the use of classical and modern two-dimensional spectral estimation techniques for enhancing inverse synthetic aperture radar (ISAR) imagery. 2-D Classical spectral estimation methods and 2-D modern parametric and non-parametric spectral estimation methods are applied to simulated and...
متن کاملThe Object Detection Efficiency in Synthetic Aperture Radar Systems
The main purpose of this paper is to develop the method of characteristic functions for calculating the detection characteristics in the case of the object surrounded by rough surfaces. This method is to be implemented in synthetic aperture radar (SAR) systems using optimal resolution algorithms. By applying the specified technique, the expressions have been obtained for the false alarm and cor...
متن کاملA Statistical Tomographic Approach to Synthetic Aperture Radar Image Reconstruction
We formulate the spotlight-mode synthetic aperture radar (SAR) imaging problem as a maximum a posteriori (MAP) estimation problem. Our statistical perspective offers an alternative to standard SAR processing techniques by incorporating prior knowledge about either the data quality or the underlying reflectivity function. In our formulation we consider exploiting the similarity between computer ...
متن کاملApplication of Displacement Map Produced by Interferometric Synthetic Aperture Radar Technique in Height Datum Determination in the Subsidence Area
Damages due to subsidence such as destruction of watering system and agricultural fertile soil, wells increasing, damage to the roads, bridges and high ways and disordering in the water and gas supplying usually are irreparable and costly. As a huge amount bench marks of height network of Iran are placed in the subsidence area, changing their heights is a challenge for NCC. In this study, a new...
متن کاملSpatial, Temporal, and Spectral Aspects of Far-Field Radar Data
We develop a linearized imaging theory that combines the spatial, temporal, and spectral aspects of scattered waves. We consider the case of fixed, distributed transmitters and receivers, and a general distribution of objects, each undergoing linear motion; thus the theory deals with imaging distributions in phase space. We derive a model for the data that is appropriate for any waveform, and s...
