Millimeter Wave Reflectivity Measurement System
Abstract
The RF Technology Section of WL/MNGS is developing an in-house capability for modeling and measurement of target scattering and material characteristics at millimeter wave (MMW) frequencies. The goal of the modeling effort is to understand the basic mechanisms that contribute to the target scattering (coated and uncoated) at MMW frequencies. The measurement effort is two-fold: verify theoretical models (target and materials) and assess the effectiveness of actual countermeasures. The MMW Reflectivity Measurement System (MRMS) is capable of bistatic swept frequency measurements for copolarized (COPOL) transmit and receive signals, and it gives a quick-look capability useful in evaluating countermeasures. The primary goal is the understanding of the various mechanisms that contribute to the scattering in order to develop the algorithms and technology necessary to exploit these effects and improve seeker guidance techniques. This paper discusses the current hardware configuration and planned upgrades and outlines the modeling effort. Examples of the MRMS measurements are compared to theoretical predictions.
