microwave-modulated 中文意思是什麼
-
The new technology of non - contact life - parameter detection is relative to that of the normal contact one, which uses microwave beams to illuminate the human subject, whose reflected wave will be modulated by the surface movement resulting from the physical activity. by this way, some parameters of the reflected wave, such as frequency and phase will be changed. if these changes can be detected, the life parameters such as respiration rate and heartbeat rate will be extracted from those changes
非接觸生命參數檢測是相對于常規的接觸式檢測而言的一種新技術，它利用微波束照射人體，其回波信號被人體生命活動引起的體表微動所調制，使得回波信號的某些參數（如頻率、相位）發生改變，檢測到這些變化就能從中提取出人體的生命參數（如呼吸或心跳） 。 -
This paper uses an optically modulated scatterer system to measure microwave field with minimal disturbance. this method is especially adapt to measure magnitude and phase of microwave field close to conductor and microwave field with complex path between source and field. so it can be used to measure radiation antenna ’ s near - field and microwave into slots
光調制散射器的測量方法最大限度地減少了測量裝置對被測場的擾動，特別適合於測量導體附近和具有復雜路徑場的幅值和相位分佈，可以用於對輻射天線近場的測試以及孔縫耦合中場的測量，可為天線的設計，微波孔縫耦合效應的研究提供較精確的實驗數據。 -
