Abstract:
1. An array device comprising: a plurality of sensors which detect a signal of a target signal source; at least one noise source; a first circuit which generates, from an output signal of said plurality of sensors, a signal having first directivity which passes a signal arriving from a direction of said target signal source; a second circuit which generates, from the output signal of said plurality of sensors, a signal having second directivity which cuts off a signal arriving from the direction of said target signal source; and a third circuit which emphasizes a signal arriving from the direction of said target signal source by correcting an output signal of said first circuit by the output signal of said first circuit and an output signal of said second circuit, wherein said plurality of sensors are disposed so as to prevent said noise source from locating at a position of a null of said second directivity calculated by using the position of said plurality of sensors and the direction of said target signal source.
