Experimental measurement of time difference of arrival [PDF]
2016 17th International Radar Symposium (IRS), 2016 In this paper is described an experimental passive localization system based on SDR (Software Defined Radio) components. This system is designed to measure Time Differences of Arrival (TDOA) of radar pulses between two platforms. For a TDOA system, time error between the two receivers must be kept very low, which requires a very accurate way to ...

IET Signal Processing, 2023 Abstract In many passive localization applications, the reference waveform of the received electromagnetic signals is partly known. The received signals in such scenarios are formulated by modelling the relationship between the received data and the known reference signal waveform and the parameters of interest, such as time ...

Contributed Review: Source-localization algorithms and applications using time of arrival and time difference of arrival measurements [PDF]
Review of Scientific Instruments, 2016 Locating the position of fixed or mobile sources (i.e., transmitters) based on measurements obtained from sensors (i.e., receivers) is an important research area that is attracting much interest. In this paper, we review several representative localization algorithms that use time of arrivals (TOAs) and time difference of arrivals (TDOAs) to achieve ...

A Fractional Programming Method for Target Localization in Asynchronous Networks
IEEE Access, 2018 In this paper, we address the target device localization problem in the asynchronous networks. For the purpose of saving power resources, the target device is not synchronized with the anchor nodes, but is only required to listen to the signals ...

A Two-Stage Method for Short-Wave Target Localization Using DOA and TDOA Measurements
IEEE Access, 2023 The ionosphere can make the short-wave source localization problem further non-linear, leading to a complicated solution process. This paper proposed a coordinated positioning algorithm based on the ionospheric virtual height (IVH) model to jointly ...
