Fidelity aspects of radar target and environment simulation

Over the last ten years, Cross Systems has been developing real-time radar target and environment simulators according to end user requirements. The authors address, in general terms, some of the simulation modeling that has been implemented in these simulators with an emphasis on the varying degrees of model fidelity, especially relative to the end user's requirements. The general trend of increasing requirements in the area of simulation fidelity is also discussed.<>
