Performance Analysis of TDOA and FDOA Location by Differential Calibration with Calibration Sources
—This paper derives the performance equation of the differential calibration algorithm using the time differences of arrival (TDOA) and the frequency differences of arrival (FDOA) with calibration sources when the positions and velocities of the receivers have random errors. By comparing the performance with the Cramér-Rao lower bound (CRLB), it proves that the ability of the differential cali...
متن کاملGeolocation using TDOA and FDOA Measurements in sensor networks Using Non-Linear Elements
Passive geo-location of communication emitters provides great benefits to military and civilian surveillance and security operations. Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA) measurement combination for stationary emitters may be obtained by sensors mounted on mobile platforms, for example on a pair of UAVs. Complex Ambiguity Function (CAF) of received comple...

15 صفحه اولData Compression Trade-offs for Tdoa/fdoa Geo-location Systems
The research results reported on here focus on new data compression methods that can enable Air Force systems to more rapidly and effectively share data for precision geolocation of RF emitters. The work was focused in four areas: (1) New Theoretical Results: We extend the previous rudimentary insight into how to use data compression to accomplish trade-offs between the sequence of tasks in a l...
متن کاملon the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors
the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
