Abstract

This paper presents a novel design of human vital sign detecting microwave radar system enlightened by a natural radar system. The system mimics the physical structure of microbat which uses the echo to detect position of its prey. In comparison with the conventional system, the inspired radar sensor system performs better in locating the position of subjects in 3D space, improving detection probability and reducing the null point problem. The theoretical model to determine the error probability of the system was investigated and matched properly with the simulation and measurement results. This work set a critical step to develop a sensing system to detect human position in 3D space.
