Optimum array filters for array data signal processing
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1983This paper deals with the design of filters for processing data obtained from arrays of sensors used for signal measurements in a variety of applications. The objective of the filters is to optimally suppress undesired signals intercepting the array, while at the same time to preserve the desired signal that the array is attempting to measure.

Array signal processing under model uncertainties
1991 IEEE International Symposium on Circuits and Systems (ISCAS), 1991Three array signal processing model error scenarios are considered: errors in sensor gains and phases, errors in sensor location, and errors in sensor-pair alignments of ESPRIT-type subarrays. The array models under the latter two error scenarios are shown to be approximately of the same form as that under sensor gains and phases provided that the ...

Event-Based Phased Array Signal Processing
Structural Health Monitoring 2019, 2019In the last few years video-based techniques for identifying the dynamic properties of structures have become of increasing interest. These techniques offer the possibility of capturing high-resolution structural dynamics information at very low cost. In recent years event-based imaging technology has also become commercially available.

Some aspects of array signal processing
IEE Proceedings F Radar and Signal Processing, 1992The paper presents an overview of some important aspects of array signal processing in the context of narrowband applications. Inverse methods for solving the array signal processing problem are reviewed. Two case studies are presented, to illustrate the various issues discussed here.

Polarimetric Array Processing for Nonstationary Signals
2004Time-frequency distributions (TFDs) have evolved to be a powerful technique for nonstationary signal analysis and synthesis. With the use of a multi-sensor array, spatial time-frequency distributions (STFDs) have been developed and successfully applied to high-resolution direction-of-arrival (DOA) estimations and blind recovery of the source waveforms.
