New Microwave Detection System and Application

摘要

A new sensitive microwave life-detection system, which operates at 1150MHz or 450Hz.This system can detect the breathing and near-beat signals of human subjects through an earthquake rubble or a construction barrier of about 10-ft thickness. A new detection system of road surface conditions, which operates at 95GHz. Using this system, the sky temperature, road surface brightness temperature and road surface temperature are measured to obtain emissivity values. In this way, it is possible to discriminate between road surface conditions ( dry, wet, water film, snow and ice).
