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.
