Modified Polar Representation (MPR) has shown its superiority in integration of near and far field localization for a stationary source. This paper extends the researches and applications of the MPR to moving source, where time difference of arrival (TDOA) and frequency difference of arrival (FDOA)…
A recent research on a fixed point iteration (FPI) algorithm for elliptic localization has shown tremendous promise in terms of reduced implementation complexity than existing algorithms without sacrificing performance [1]. However, no theoretical analysis was provided in this study. In this article…
Multidimensional scaling (MDS) is an attractive method for location-related applications due to its robustness against noise. This paper applies MDS to time difference of arrival (TDOA) localization in the modified polar representation (MPR) for integrating near-field and far-field localizations. Th…
Linear array-based three-dimensional (3-D) localization is a recently proposed technology. It uses a set of newly defined one-dimensional (1-D) angles, called space angle (SA), to locate the source. Integrating SA with time difference of arrival (TDOA) promises higher accuracy, and more attractive,…
Recent research has shown that using the 1-D signal arrival angles observed by linear arrays can locate a 3-D source in unique co-ordinates. Current methods to solve this localization problem are based on semidefinite programming (SDP) or gradient-based iteration, which are either computationally de…
Time difference of arrival (TDOA) point positioning in the Cartesian coordinates is practical for a near-field source, and it will suffer from the thresholding effect when the source is in the far-field where only direction of arrival (DOA) can be obtained. Localization in the modified polar represe…
