In the paper, an idea of a method of signal arrival direcfion esfimafion is presented. The
influence of fime error measurements on the usage of the method is described. An approach …

The paper presents and discusses a method of azimuth determination of ultrasonic echo
arrival in air. The basis of the presented approach is the assumption that the received signal …

This paper addresses some selected techniques for direction of arrival estimation using air-
coupled ultrasound and custom hardware computational solutions. The main issue of the …

The paper presents a method of echo azimuth angle estimation for ultrasonic range finders.
The method is based on phase shift determination. Because of size of applied transducers it …

The problem of incident angle determination for an ultrasonic signal is the main concern of
this paper. The problem is considered for a 2-D case when the azimuth angle of echo arrival …
