Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed a body movement elimination technique using phase differential technique for vital sign radar, where the BF (Beamforming) weights determine its detection performance.
This paper proposes a method to automatically generate BF weights from the received signal.
First, the proposed method extracts the frequency components corresponding to heartbeat and body movement from the received signal and computes a correlation matrix from each component.
Then, weight #1, which forms a beam to the heartbeat components, and weight #2, which forms a null to the heartbeat components and acquires the body movement components, are generated.
Weight #1 is computed from the first eigenvector of the correlation matrix containing the heartbeat components.
Weight #2 is computed based on the Rayleigh quotient to maximize the ratio of the received power of the body movement components to that of the heartbeat components.
Finally, the body movement components are eliminated by performing BF with computed weights and taking the difference of the phase components of two output signals.
Simulation results showed that the proposed method can generate the desired weights.
Moreover, the heartbeat response estimated by the proposed method had a correlation coefficient of 0.993 with the ground truth.
