Development on Human Detection System using Digital Terrestrial TV Waves

为了开发基于地面电视广播电波的人体检测系统，本研究主要做了以下三个方面的工作：(1)提出并发展了多路检测方法，对数字电视解调过程中获得的载噪比(CNR)和误码率(BER)同时进行监测，以提高检测性能。(2)为减少室外干扰造成的误检，提出并开发了室内和室外天线设置的协同检测方法。(3)明确了下一步地市电视波的越界传播特征，实现了人体探测系统的稳定运行。

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.
