Device for measuring walking gait characteristic of human body

Abstract

The invention relates to a device for measuring the walking gait characteristic of a human body. The device comprises a highly stable microwave signal source, a continuous wave transmitter, a circulator, a transceiving antenna, an amplifying, mixing and receiving channel, a signal processor and a parallel data processing and display terminal, wherein the output of the highly stable microwave signal source provide a stable signal for the continuous wave transmitter; the continuous wave transmitter is connected with the circulator, transmits a microwave signal to the transceiving antenna and transmits the microwave signal through the antenna; the transceiving antenna receives a reflection echo from a target and transmits the reflection echo to the amplifying, mixing and receiving channel through the circulator; the output of the amplifying, mixing and receiving channel is transmitted to the signal processor; the signal processor converts an analog signal into a digital signal and performs digital filtering and time frequency processing; and the processed digital signal is connected with the data processing and display terminal. The device can realize gait identification, extracts the gait characteristic of a pedestrian a certain distance away, and has non-compulsivity and acceptability.

Description

Technical field: [0001] The present invention relates to a measuring device, in particular to a radar device capable of measuring human body gait characteristics, that is, a human body walking gait characteristic measuring device. Detect and classify objects of interest in a wide range of people at a range. Background technique: [0002] Biometric authentication technology, as a high-tech that began to flourish at the end of the 20th century, occupies an increasingly important position in social life. At present, the identification and authentication methods such as iris, face, fingerprint, and DNA are mainly used in the identification of people of interest at close range, but the ability to detect and identify objects of interest in a wide range of people at a certain distance is poor. The gait characteristics of a person reflect the movement characteristics of various parts of the body; it is a habit formed by the human body for a long time walking, which is difficult to ...
