Array processing is signal processing of the outputs of an array of sensors to: * Enhance the SINR|signal-to-interference-plus-noise ratio (SINR) compared to that of a single sensor using conventional or adaptive beamforming. * Determine the number of emitting sources, the locations of these sources, their waveforms, and other signal parameters. * Track multiple moving sources. Array processing is used in radar, sonar, seismic exploration, anti-jamming and wireless communications. One of the main advantages of using array processing along with an array of sensors is a smaller foot-print. The problems associated with array processing include the number of sources used, their direction of arrivals, and their signal waveforms. There are four assumptions in array processing. The first assumption is that there is uniform propagation in all directions of isotropic and nondispersive medium. The second assumption is that for far field array processing, the radius of propagation is much...
