A subsystem of a tactical information system is provided that includes a memory configured to store instructions and a processor disposed in communication with the memory. The processor, upon execution of the instructions is configured to receive first standardized entity messages that include target information from multiple automatic target recognition (ATR) systems, parse the first standardized entity messages to extract the target information, provide the extracted target information to a fusion algorithm for fusion processing that determines whether to fuse the target information from different ATR systems and fuses the extracted target information to generate fused target information about a single target when determined to do so, receive fused target information about the single target, if any, from the fusion algorithm, and generate a second standardized entity message that includes the fused target information about the single target.
