Radar detection device employing a scanning antenna system
First Claim
1. A system for detecting a respiration signal of at least one subject in a target area, comprising:
- a scanning antenna to transmit a microwave signal across the target area, wherein the scanning antenna receives a reflected microwave signal from the at least one subject;
a control system to track the position of the scanning antenna as the scanning antenna transmits the microwave signal while the position of the scanning antenna mechanically and continuously rotates;
a signal processing system to detect the respiration signal of the at least one subject from the reflected microwave signal that is received by the scanning antenna.

Abstract
Systems and methods for detecting a respiration signal in a target area are disclosed. Briefly described, in architecture, one embodiment of the system, among others, can be implemented as follows. The system includes a scanning antenna configured to transmit a microwave signal across a horizontal axis in the target area. Also, the system includes a control system that tracks the position of the scanning antenna along the horizontal axis. A signal processing system then detects a respiration signal of a living subject in the target area from reflected microwave signals from the target area and the positional data. Other systems and methods are also provided.
