Modal Analysis Using Sparse and Co-prime Arrays
Let a measurement consist of a linear combination of damped complex exponential modes, plus noise. The problem is to estimate the parameters of these modes, as in line spectrum estimation, vibration analysis, speech processing, system identification, and direction of arrival estimation. Our results differ from standard results of modal analysis to the extent that we consider sparse and co-prime...
متن کاملSpecial issue on Co-prime sampling and arrays
Co-prime sampling and co-prime arrays have recently been shown to improve active and passive sensing in radar and underwater acoustics using both narrowband and wideband signal platforms. Co-prime processing provides a systematical framework for sparse sampling and array configuration with increased aperture and improved spatial resolution. Co-prime based approaches to sampling and arrays can c...
متن کاملSparse reconstruction for direction-of-arrival estimation using multi-frequency co-prime arrays
In this paper, multi-frequency co-prime arrays are employed to perform direction-of-arrival (DOA) estimation with enhanced degrees of freedom (DOFs). Operation at multiple frequencies creates additional virtual elements in the difference co-array of the co-prime array corresponding to the reference frequency. Sparse reconstruction is then used to fully exploit the enhanced DOFs offered by the m...
متن کاملCo-inference for Multi-modal Scene Analysis
We address the problem of understanding scenes from multiple sources of sensor data (e.g., a camera and a laser scanner) in the case where there is no one-to-one correspondence across modalities (e.g., pixels and 3-D points). This is an important scenario that frequently arises in practice not only when two different types of sensors are used, but also when the sensors are not co-located and ha...
متن کاملModal Analysis Turboshaft Test Stand Motor Designed by Using ANSYS
Today, modeling is critical for cognition and analysis of designers in industry field to meet their needs and design based on design requirements and available facilities to accelerate production and development of components of industrial engines. In this study, one structure has been proposed, designed, and analyzed based on turboshaft marine engine type to test this kind of engine in order t...
