General direction-of-arrival tracking with acoustic nodes [PDF]

In this paper, we propose a particle filter acoustic direction-of-arrival (DOA) tracker to track multiple maneuvering targets using a state space approach. The particle filter determines its state vector using a batch of DOA estimates.

Experimental validation of spatial spectrum suppression algorithms for interference sources

Dianzi Jishu Yingyong
In the actual direction finding system, when the weak signal and the strong interference are spatially close, the spatial spectrum direction finding system can only estimate the direction of arrival (DOA) for the strong interference, and the performance ...
