Recently, direction position determination technology for multiple sensor arrays has been considerably attractive in wireless communication, radar, sonar, radio astronomy, and seismology. Unlike the conventional two-step location approach, the direct position determination method does not need to estimate the measurement parameters and perform step-by-step calculation of the position. The method can directly acquire the source position from sensor outputs in a single step.

This Special Issue is intended to encourage high-quality research in direction position determination technique and its applications to wireless communications, radar, sonar, radio astronomy, seismology, and other fields. New research works are invited to tackle the potential problems in emerging applications of direction position determination technology. Topics discussed can be in terms of concepts, the state of the art, implementations, and running experiments or applications.

The purpose of this Special Issue is to gather state-of-the-art research contributing to recent advances in the field of direction position determination technology for multiple sensor arrays. Original research and review articles are welcome.

Potential topics include but are not limited to the following:

• Direct position determination for multiple sensor arrays via the properties of the received signals, such as modulus, noncircular and cyclostationary
