Radar systems for detection of human heartbeats have mostly been single-channel systems with limited spatial resolution. In this paper, a radar system for ultra-wideband (UWB) imaging of the human heart is presented. To make the radar waves penetrate

This paper presents the design of an X-band 8×8 digital array radar antenna with aperture-coupled stacked patch antenna elements. The use of a resonant aperture and stacked patches resulted in a -10 dB reflection coefficient bandwidth of 7.6-12.8 GH

When evaluating the performances of radar waveforms, it is crucial to understand how the signal is affected by multiple interactions with the environment and the system hardware. Analysis of complex radar systems, such as multistatic and netted desig

In this paper the optimal frequency range for heartbeat measurements using body-contact radar is experimentally evaluated. A Body-contact radar senses electromagnetic waves that have penetrated the human body, but the range of frequencies that can be

Radar can be used to detect human heartbeats. This makes radar a potential alternative to today's heartbeat monitoring techniques in medicine. In this paper, two antennas were located on the chest to monitor the heart activity. Simultaneous with the

Heartbeats can be measured at a distance using radar to record the chest movements. The physiological motion appear as modulations in both phase and amplitude in the radar recording. In this paper, a single reflector model of the heartbeat is used to
