Abstract

A novel measurement technique for simultaneous remote range and temperature determination that utilizes the microwave (10.0 GHz) backscatter from a traveling ultrasound wave (about 22 kHz) is discussed. Such a system is operated in a closed environment which suffers from clutter echoes. Maximum range of about 30 m can be measured with an accuracy of better than 1%. Multiple targets are detectable with a resolution of at least 2%. The air temperature profile along the path can be determined with the same local resolution and with an accuracy of better than +or-0.10 degrees C.<>
