HWIL testing typically requires the implementation of a multi-target motion simulator such as the Ideal Aerosmith Model 244SE-10. The Target Motion Simulator (TMS) is housed in an anechoic RF chamber and anchored to a rigid wall or equivalent structure.  An Ideal Aerosmith Three-Axis FMS is mounted on a track assembly at the opposite end of the chamber so that FMS may be withdrawn from the chamber port for missile seeker installation, setup and servicing.

The TMS moves a front payload (RF source, target) through a spherically-curved locus of 10 m radius originating on the FMS axis intersection such that the payload remains pointed at this intersection.  The TMS independently moves a rear payload through a similarly oriented spherically-curved locus of 11.6 m radius.
