Abstract

This paper discusses a Dual Mode Hardware-in-the-Loop simulation facility developed for the dynamic evaluation of IR/RF dual mode seekers. A unique concept combines the collimated target images from an Infrared Scene Simulator and an RF Target Projector using an IR/RF "dichroic" and reflects/transmits to the seeker under test. The combined IR/RF target scene generator is mounted on a two axis target motion simulator. The dual mode seeker is mounted in a three axis flight simulator, allowing the missile-to-target scenario to be simulated across wide dynamic conditions. The paper will discuss the Infrared Scene Simulator including the design constraints due to the physical/dynamic operating environment, the target characteristics, and the properties of the IR/RF target combining dichroic. The RF Target Projector will be described including the design goals for range performance, and the RF feed horn system. System performance characteristics will be described including computer simulations of the RF Target Projector performance and laboratory tests of the Infrared Scene Simulation.
