Prediction of array gain in directional noise field

Abstract

The Array Gain (AG) is a metric to assess the performance of an array, and is dependent on the configuration of array, frequency, as well as on the directionality of noise. In this study, AG is calculated based on the spatial coherence between sensor elements in directional noise environment for a given array shape. The estimated AG is then compared with AG derived from the sea going data based on the signal to noise ratio. The results are presented and discussed.een sensor elements in directional noise environment for a given array shape.
