A continuing question asked of MMW target signature and model providers is the applicability of data from one
frequency band to another. Recent monopulse Ka-band ground target signature measurements made by US Army
programs provide an opportunity to do an in-depth comparison of signatures of several ground vehicles. The vehicles
measured correspond to those measured at W-band by another Army program. This paper provides a comparison of
vehicle signatures produced by models derived by AMRDEC from the measurements. The results have implications for
missile programs that do not have an extensive measurement budget but require target signatures and models for
algorithm development.

The development of a modularized millimeter wave (MMW) target and background high resolution scene generator is reported. The scene generator's underlying algorithms are applicable to both digital and real-time hardware-in-the-loop (HWIL) simulations. The scene generator will be configurable for a variety of MMW and multi-mode sensors employing state of the art signal processing techniques. At present, digital simulations for MMW and multi-mode sensor development and testing are custom-designed by the seeker vendor and are verified, validated, and operated by both the vendor and government in simulation-based acquisition. A typical competition may involve several vendors, each requiring high resolution target and background models for proper exercise of seeker algorithms. There is a need and desire by both the government and sensor vendors to eliminate costly re-design and re-development of digital simulations. Additional efficiencies are realized by assuring commonality between digital and HWIL simulation MMW scene generators, eliminating duplication of verification and validation efforts.

Turntable data collection on ground targets using an instrumentation W-band monopulse radar is reported. The data collection site, instrumentation, and test methodology are described. Preliminary analysis results showing target RCS comparisons are reported. The turntable measurements are used to generate point scatterer target models for all-digital and real-time hardware-in-the-loop (HWIL) simulations. Model development techniques are described. The models are validated against measured data utilizing generic high range resolution acquisition and tracking algorithms.
W-band monopulse stepped-frequency turntable measurements are reported. Data collection site, instrumentation, and test methodology are described in detail. The turntable measurements are used to generate point scatterer target models for all-digital and real-time HWIL simulations. Model development techniques are described. The models are validated against measurement data utilizing generic high range resolution acquisition and tracking algorithms. Validation methods and results are presented. Polarimetric signatures and modeling results for two ZIL-131 trucks measured in different configurations are compared. One truck has a canvas-covered bed, and the other, a command post vehicle, has a metal-covered plywood box structure on the back. Model implementation in assessment of seeker acquisition algorithms will determine capability to reject the trucks as low-value targets.
