  1. 36. Feasibility Study for Single Platform Airborne FDOA and TDOA Estimation With Unknown Source

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Alexander Karlsson; [2016]
    Keywords : ;

    Abstract : Direction of arrival (DOA) estimation is a well studied topic and used in many different applications. Although it is usually based on time-difference-of-arrival (TDOA) of coherent signals, it is sometimes possible to also use frequency-difference-of-arrival (FDOA). By combining TDOA and FDOA a more reliable estimate of the DOA can be obtained. READ MORE

  3. 37. Multi-Frequency Direction of Arrival Estimation by Low-Rank Approximation

    University essay from Lunds universitet/Matematik LTH

    Author : Linus Jangland; [2016]
    Keywords : Direction of arrival estimation; Hankel matrices; low rank; optimization; Mathematics and Statistics;

    Abstract : We consider the problem of estimating the location of a number of wave-emitting sources, known as the direction of arrival problem. We consider both the two- and three-dimensional case. The method we use works for equally as well as unequally spaced sensors, that are located in (possibly) non-square regions. READ MORE
