Type-Agnostic RF Signal Representations

摘要

This document describes techniques and devices for type-agnostic radio frequency (RF) signal representations. These techniques and devices enable use of multiple different types of radar systems and fields through type-agnostic RF signal representations. By so doing, recognition and application-layer analysis can be independent of various radar parameters that differ between different radar systems and fields.

主权项

1. One or more computer-readable storage media having instructions stored thereon that, responsive to execution by one or more computer processors, implement an abstraction module and a recognition module:
the abstraction module configured to:
receive different types of type-specific raw data, each of the different types of type-specific raw data representing a reflection signal made by an object moving within a different type of type-specific radar field; andtransform each of the different types of type-specific raw data into a type-agnostic signal representation, and the recognition module configured to:
receive the type-agnostic signal representations; anddetermine, for each of the type-agnostic signal representations and based on the type-agnostic signal representations, a gesture or action performed by the object within the respective different type of type-specific radar field.
