When electromagnetic waves irradiate the human chest, minute displacements caused by breathing and heartbeat will lead to frequency shifts in the reflected waves. Respiratory detection is relatively easy because abdominal motion is more pronounced; heartbeat detection is more difficult because the body surface changes caused by heartbeat are much smaller, approximately one-tenth or one-hundredth of those caused by
