Abstract

Sparse interferometer array systems can be the cost-effective precision radio-frequency emitter directionfinding systems needed in military and civilian applications. High precision can be implemented by array extent, while low cost is supported because the array is sparse. However, in the design process ambiguities in the high dimensional array manifold space need to be evaluated, which typically can be mathematically or empirically daunting. Here we describe a method to collapse the high dimensional design space, using root-mean-squared phase differences for signals received at pairs of elements in the interferometer, to a twodimensional histogram for ambiguity visualization and evaluation (HAVE). The histogram facilitates design by presenting and locating interferometer ambiguities.
