摘要/Abstract

摘要： 设计了一个能够提取人体微波心动图的“微波心动图仪”.该仪器使用1 150 MHz微波连续波作为载波信号，用计算机控制的零平衡方法进行未调制载波抵消，用检测前向散射波(透射波)的方法绘制心动图.所研制的样机具有结构简单、灵敏度高、噪声小的特点.还给出了该样机采集的微波心动图样例，并进行了讨论.

Abstract: A design of Microwave Cardio Graph Meter (MCG)，by which human signal can be extracted is proposed in this paper. Features: 1 150 MHz continuous ca rrter wave; Cancellation of un-modulated carrier wave by Zero-balance technique; Using forward scattering wave to improve performance. Experiments show that: the apparatus is simple in structure, and works steadily with high sensitivity and low noise. The MCG graphs are presented and discussed in detail.

Key words: forward scattering, cancellation of un-modulated carrier wave, microwave cardio graph, forward scattering, cancellation of un-modulated carrier wave
