Non-Coherent Direction of Arrival Estimation via Frequency Estimation
This letter investigates the non-coherent Direction of Arrival (DOA) estimation problem dealing with the DOA estimation from magnitude only measurements of the array output. The magnitude squared of the array output is expanded as a superposition of some harmonics. Hence, a frequency estimation approach is used to find some nonlinear relations between DOAs, which results in inherent ambiguities...
متن کامل‘Direction of Arrival’ Estimation Algorithm: Direction Lock Loop
In this paper, a new direction of arrival (DOA) estimation algorithm, direction lock loop (DiLL), is proposed. It has a similar concept to the delay lock loop (DLL) that is used for synchronization. It estimates the DOA of a signal by iterations, and can track the DOA of a moving source. The DiLL scheme is found to track better than the DOA estimation scheme based on the PASTd, and its performa...
متن کاملDirection of Arrival Estimation
We have seen that there is a one-to-one relationship between the direction of a signal and the associated received steering vector. It should therefore be possible to invert the relationship and estimate the direction of a signal from the received signals. An antenna array therefore should be able to provide for direction of arrival estimation. We have also seen that there is a Fourier relation...
متن کاملDirection of Arrival Estimation
Array Signal Processing (ASP) is a relatively new technique in Digital Signal Processing (DSP) with many potential applications in communication and speech processing. Direction of arrival (DOA) can be estimated using different techniques evolved with ASP. It is observed that subspace method provides superior performance in resolving closely spaced sources.
متن کاملUnderdetermined direction-of-departure and direction-of-arrival estimation in bistatic multiple-input multiple-output radar
In this paper, target localization using bistatic multiple-input multiple-output radar where the source number exceeds the sizes of the transmit and receive arrays, denoted by M and N, respectively, is addressed. We consider the Swerling II target in which the radar cross section varies in different pulses. Two algorithms for joint direction-of-departure (DOD) and directionof-arrival (DOA) esti...
