Radar target simulation of space object

This paper describes a target simulation which operates in non real-time to provide full closed-loop operation of the ground based multifunction phased array radar simulation system in support of ballistic missile defence experiments against countermeasure. By simulating the target scattering signature and dynamical signature, this target simulation provide realistic scenario source to evaluate the system performance of multifunction phased array radar, and the key algorithms verification and validation such as target tracking, multi-target imaging and target recognition.
