Analysis of Prospective Directions for Development of Systems Using Reflection or Secondary Radiation of Acoustic Waves

Abstract

In this work, to identify promising areas for the development of electronic systems using reflection or secondary radiation of acoustic waves, a patent analysis method is used based on the formation of time series of US patents and comparison between different technical solutions for the number of patents registered in specific subgroups of the International Patent Classification (IPC), and the dynamics of their issuance in the interval 2010–2019. The use of the IPC allows an effective search and classification of any technical solution, a retrospective analysis, as well as the formation of predictive assessments of the development of technologies, involving open resources of various patent offices. As a result of the study, data were obtained that suggest that all systems using the reflection of acoustic waves have been successfully developing for the past ten years. The most promising among them are systems using reflection of acoustic waves and systems specially designed for special applications. Among systems with reflection of acoustic waves, the most promising systems are systems for determining the location of a target by measuring only range using transmissions of intermittent pulse-modulated signals.
