PHASE RATE OF CHANGE TECHNIQUES FOR PASSIVE GEO-LOCATION OF RADIO FREQUENCY EMITTERS

摘要

The present invention relates to a system for solving the phase ambiguities in the phase change rate (PROC) for measuring janggiseon interferometer (LBI). The system includes a processor that is disposed upon the LBI, and transport means including a first antenna and a second antenna located on a vehicle to receive the RF signal transmitted by the RF emitter. Processor RF been to produce a short distance range estimation of the emitter, so as to determine a first phase the rate of change (PROC) of the RF signal received by the LBI for a short time interval, RF already generate a plurality of ambiguous long time interval range estimate of the emitter , it is configured to determine the 2 PROC of the RF signal received by the LBI for greater long time interval a short time interval, and c) to select one of a plurality of the long time interval range estimated based on a short time interval range estimates to.
