Abstract

We propose a method for designing a mechanical modulator for an uncooled subterahertz radiometer capable of operating under prolonged expeditionary conditions. The modulator enables periodic modulation of thermal radiation from the observed object directly in front of the radiometer’s receiving antenna and provides mechanical scanning within an angular range from 0° to 90°. As a matched reference load, an absorber fabricated via 3D printing from a composite polymer with high electrical conductivity is used.
