Curved sensor array configurations ( 702, Figures 1 A, 2A, 2B, 8A, 8B, 8C , 9, 10, 11) and methods (Figures 6A, 6B, 6C) of processing the data gathere d by the sensors. A 2 dimensional embodiment (Figure 1 A) comprises singular ring of sensors that can monitor sources in a 2 dimensional plane. A sensor directly facing a target produces a maximum response (Figure 1 C). As the a ngle of a sensor relative to the target increases, the response decreases. F itting the sensor response amplitudes.to a 2D Gaussian curve (Figure 1 B) an d calculating the peak of the curve (606) allows a very accurate calculation of the angular direction (608) of the target. A 3D embodiment (Figures 2A, 8A, 8B, 8C) comprises sensors scattered over the surface of a sphere in orde r to monitor multiple targets in any spatial orientation. Again, the sensor amplitude data is fitted to a 3D curve or surface such as a Gaussian surface (Figure 2C). The present invention can resolve more than one target using d econvoluting techniques (622, Figures 4A, 4B, 4C, 5A, 5B, 5C, 5D).
