Abstract
At least two receiver sets are provided. A data processor is in communication with the receiver sets, wherein the data processor tags position data and radio frequency emission data from the receiver sets. A data storage unit is in communication with the data processor and is at least capable of storing tagged data. A processing unit is capable of processing the tagged data. The processing unit defines a search grid within which to search for the source of the radio frequency emission. The processing unit motion compensates the tagged data separately for each point on the grid. The processing unit assigns a value to each grid point based on a phase coherence of the motion compensated data. The processing unit determines a location within the grid having a highest assigned value, thereby determining the source of the radio frequency emission.
