Direction of arrival estimation with sensor arrays

Abstract

With recent increase of hardware capabilities, the application of sensor arrays in the Direction-Of-Arrival estimation is gaining more and more popularity. The behaviour of the array is the complex function of the geometry, sensor characteristic, signal and noise properties and other different factors. Before building the array it is essential to simulate its performance in different conditions with different algorithms. Most of the time the simulations are performed using custom ad-hoc created code. This code is error prone and difficult to maintain. Our goal was to create a reusable and extensible library that would provide the components used in the simulation process. In this paper we present the initial version of the library along with several illustrative examples.
