Radar based human vital sign detection in cars: Signal processing

In this thesis signal processing techniques for the Ultra-wide-band impulse radar (UWB-IR) radar are dis-cussed. To context wherein these algorithms are used is in a car, with the aim of detecting a child left behind in the car. This thesis also touches on algorithms to obtain vital information of the child inside the car. To this end a...

Radar Based Human Vital Sign Detection In Cars: A System Analysis

This thesis analyses different radar systems for sensing chest movement to detect human presence inside a car. The detection in this thesis is limited to sensing breathing rate, although heartbeat detection is considered a possibility. A comparison is made between CW-, FMCW-, pulsed- and UWB pulsed radar. UWB pulsed radar was chosen to be a...

Design of Frequency locked loop and Receiver front-end for Burst-Chirp UWB Radar Transceiver for Vital Signs and Occupancy Sensing by monitoring the respiration and heartbeat rate

While there are many technologies and electronic systems used to detect the human vital signs by monitoring the heart beat rate & respiration rate, all these systems rely on physical contact with the human body. Furthermore, each measuring system can only be used for a single person thus increasing the cost and complexity of integrated...

Target localisation and tracking in a UWB radar network: UWB Indoor Person Tracking

For both security and analytics, much research has gone into person tracking already. As a result, many<br/>different state of the art technologies exist. However, in darkness or without a direct line of sight, much<br/>less technologies are capable of this. The choices become especially limited when the setup needs to<br/>be portable.<br/>A...

Ultra Wideband Synthetic Aperture Radar Imaging: Imaging algorithm

Nowadays, localization of cars is mostly done using GPS. Some major disadvantages of this method are that it is not very accurate and that it cannot be used indoors. These disadvantages do not form a major problem when an active human driver is controlling the car, but will become more critical when the autonomy of vehicles increases. The goal...

Ultra Wideband Synthetic Aperture Radar Imaging: Data Acquisition & Antenna Analysis

A system has been developed that utilises the techniques of Ultra Wideband and Synthetic Aperture Radar to produce top view images of a scene using measurements from the side. The system consists of the PulsON P410 radar module, a set of antennas, a moving platform and an imaging algorithm. This thesis will cover all the aspects of the data...

UWB FMCW Radar for Concealed Weapon Detection: RF front-end development

Current methods for concealed weapon detection are mainly used at stationary security check-points due to complexity and other serious limitations for real-time outdoor scenarios. A mobile imaging radar is considered as a proper solution for fast screening of people at mass events because of its ability to detect both metal and non-metal weapons...
