Special Issue Information

Dear Colleagues,

Sensors in automation and robotic devices are very important. Their speed, accuracy, and measurement range in an essential part determine the characteristics of the entire automation device or robotics as a whole. The development of methods and measuring instruments for this reason determine the progress in this direction of technology. Such sensors should have the highest possible response speed and high accuracy, reliability, reproducibility of their characteristics, low noise, and displacement. The scientific exchange of information on the latest advances in high-speed sensors and their applications is extremely relevant. Of interest are reports on the expansion of the scope of sensors and on methods for improving them, as well as on technologies for creating new sensors, methods of their certification, calibration, and so on.

The XV International Scientific and Technical Conference «Actual Problems of Electronic Instrument Engineering» (APEIE 2021)(https://apeie.conf.nstu.ru/) is one of the leading events reporting research results on all scientific aspects of electrical, electronic and radio engineering, semiconductor nanotechnology, optical systems, meas-uring technologies, as well as their relevant industrial trends. This Special Issue is devoted to these works. Authors of all accepted papers relevant to topics  presented at APEIE 2021 are invited to submit an expanded version of their accepted conference paper to the Special Issue.

The purpose of this Special Issue is also to present the latest advances in technology for the creation and use of physical sensors. Contributions to all areas of metrology are welcomed, including new measurement signal processing methods, sensor activation methods, methods to improve their accuracy, smart sensors, and new applications. Those include but are not limited to:

  • Sensors;
  • Measurements in robotics;
  • Measurements in automation;
  • Autonomous control systems;

This paper considers the application of signal processing methods to passive indoor positioning with acoustics microphones. The key aspect of this problem is time-delay estimation (TDE) that is used to get the time difference of arrival of the source’s signal between the pair of distributed microphones. This paper studies the approach based on generalized phase spectrum (GPS) TDE methods. These methods use frequency-domain information about the received signals that make them different from widely applied generalized cross-correlation (GCC) methods. Despite the more challenging implementation, GPS TDE methods can be less demanding on computational resources and memory than conventional GCC ones. We propose an algorithmic implementation of a GPS estimator and study the various frequency weighting options in applications to TDE in a small room acoustic environment. The study shows that the GPS method is a reliable option for small acoustically dead rooms and could be effectively applied in presence of moderate in-band noises. However, GPS estimators are far less efficient in less acoustically dead environments, where other TDE options should be considered. The distinguishing feature of the proposed solution is the ability to get the time delay using a limited number of the adjusted bins. The solution could be useful for passively locating moving emitters of narrow-band continual noises using computationally simple frequency detection algorithms. Full article
