Improving the resolution of a sensor array pattern by neural networks

摘要

The sensor array pattern is the spatial response of an array of sensors to an incident monochromatic plane wave. It is known to have a resolution which is a function of the number of sensors. In some applications the number of sensors may be small for technical or economical reasons. The authors present and analyse a feedforward neural network structure which is able, by learning, to improve the resolution of the array pattern for a fixed and small number of sensors.
