Solution Overview

Problem

Existing radar technologies struggle to identify the specific object to which measured information belongs during the measurement of multiple objects.

Innovation Solution

A physiological information monitoring radar system processes reflected radar signals to obtain response characteristics and range information, distinguishing these characteristics as identification or physiological information, and labels them accordingly using a frequency modulated continuous wave radar.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If radar technology measures multiple objects, then measurement capability is improved, but ability to identify specific object is lost

Engineering Contradiction:

Improvemeasurement capabilityVSAvoidobject identification information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent segments the measurement process by introducing response devices that are attached to or integrated with specific objects. Each response device carries identification information that allows the radar system to segment and attribute measured data to specific objects, thereby maintaining object identification capability while measuring multiple objects simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The response device acts as an intermediary between the radar system and the objects being measured. It receives incident radar signals, processes them, and generates reflected signals containing identification information, enabling the radar system to identify which object each measurement corresponds to

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A monitoring radar and a monitoring and identification method therefor are provided. The monitoring radar may be a physiological information monitoring radar. The monitoring and identification method may be a physiological information monitoring and identification method. The physiological information monitoring radar processes at least one reflected radar signal to obtain a response characteristic and range information corresponding to each of a plurality of to-be-monitored objects and distinguishes the response characteristic of each of the to-be-monitored objects as identification information or physiological information. The physiological information monitoring radar then labels each piece of physiological information according to the range information and the identification information.
