An analog associative processor for discriminating between intersects representing targets and intersects representing ghosts from angle-only information from multiple sensors. The analog associative processor is constructed using a multi-layer substrate that is an analogue of the real-world sensor emplacements, angular sensor traces, and coordinate system. A method is implemented by the analog associative processor which detects ghosts by counting (20, 22) pulses received by each intersect from the other intersects. When the number of pulses reaching a given intersect reaches a predetermined threshold (T3), the intersect is identified as a ghost. The analog associative processor then continues (26) until the number of remaining intersects equals the number (N) of total targets. The remaining intersects are then identified (28) as true targets. The analog associative processor is faster than conventional software solutions to deghosting problems and contains few components so that it is inexpensive to manufacture (Fig. 3). |
