| Research Abstract |
In order to develop our proposed human detection system using terrestrial TV broadcasting waves, this study evaluated following main three subjects; (1)The multiple detection method was proposed and developed, which simultaneously monitored CNR (Carrier to Noise power Ratio) and BER (Bit Error Rate) obtained in the digital TV demodulation, for the purpose of improving detection performance.(2) To reduce false detection caused by outdoor disturbance, the cooperated detection method was proposed and developed, in which the antennas were set up both indoor and outdoor. (3) This study clarified characteristics of overreach propagation in TV waves from next prefectures, to realize stable operation of the human detection system.
