Closed-Form Method for Unified Far-Field and Near-Field Localization Based on TDOA and FDOA Measurements

open access: yesRemote Sensing
When the near-field and far-field information of a target is uncertain, it is necessary to choose a suitable localization method. The modified polar representation (MPR) method integrates the two scenarios and achieves a unified localization with ...

A Distributed Low-Degree-of-Freedom Aerial Target Localization Method Based on Hybrid Measurements

open access: yesRemote Sensing
For real-time detection scenarios such as battlefield reconnaissance and surveillance, where high positioning accuracy is required and receiving station resources are limited, we propose an innovative distributed aerial target localization method with ...

Implementing the cross ambiguity function and generating geometry-specific signals [PDF]

open access: yes, 2001
The first purpose of this thesis is to implement an efficient Cross Ambiguity Function (CAF) algorithm to compute the Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA) between two sampled signals.

Optimal frames and Newton's method

open access: yes, 2012
Given a parametrized family of finite frames, we consider the optimization problem of finding the member of this family whose coefficient space most closely contains a given data vector.
