Abstract:
The present disclosure provides an RTD that is released from a single primary platform to collect signals from a target emitter and relay data back to a single primary platform, enabling the precise geo-location of the target emitter to be determined in a minimal amount of time. The RTD is released from a single platform and quickly creates a long signal collection baseline between the released RTD and the single platform. Various techniques for determining geo-location may be used with the present disclosure, such as angle of arrival (AOA), time difference of arrival (TDOA), and frequency difference of arrival (FDOA) methods.
