Abstract: A new two-dimensional spatial spectral estimation direction finding method based on L-shaped array and time modulation theory is proposed. The main principle of this method is to generate a ...

Abstract: Aiming at the typical environment of underwater target passive positioning, the performance of a two-dimensional DOA estimation method based on L-shaped array is simulated. Firstly, the ...

For the first time, researchers have shown that self-assembled phosphorus chains can host genuinely one-dimensional electron behavior. Using advanced imaging and spectroscopy techniques, they ...
