Phase difference of arrival range estimation technique
Range estimation is an integral part of all localization techniques. range information is usually inferred from strength of received signal, time of arrival and time-difference of arrival. the uncertainty in estimation may be caused by noise and multipath effect. this work focuses on range estimatio...

| description | Range estimation is an integral part of all localization techniques. range information is usually inferred from strength of received signal, time of arrival and time-difference of arrival. the uncertainty in estimation may be caused by noise and multipath effect. this work focuses on range estimation on the basis of phasedifference of arrival (pdoa) where the target source employs a dual-frequency transmission as in case of dual-frequency radars. the range estimation in this technique is constrained by the difference in frequency and the level of synchronization between the two transmitted signals. in order to quantify the impact of these two limitations, a measurement setup, based on usrp (universal software radio peripheral) devices will be used. two synchronized collocated usrp transmitters will be used as source and another usrp (with two receivers) will be used for range estimation at a distance. the measurements will be taken in a line-ofsight environment. the final report would present the results of simulation showing the relation between frequency difference and maximum unambiguous distance. a comparison between simulation results and field measurements will then be presented. the conclusions drawn from the data would pave the way for further investigation in multipath environment |
