Abstract
The system and method of copy aided geolocation in a cochannel environment. The plurality of emitter signals are detected using a multichannel antenna array, separated into subbands based on frequency ranges using a channelizer, and are further processed using copy weights, property restoral algorithms, and maximum likelihood calculations. The multichannel antenna array may be mounted to a mobile platform and the calculations may assume that the signal of interest is non-Gaussian, but the remainder of emitter signals is combined into another signal that is assumed to be Gaussian. The method and system provides geolocation results that adhere to the Cramer-Rao bound.
