Abstract:

Modeling the stochastic nature of an air-to-ground radar imposes stringent demands on the processor required to implement the simulation. These demands are intensified when the simulation environment must fit the timeline of a real-time radar system. This paper examines a method to model the stochastic nature of the radar system in a Moving Target Indicator MTI mode using ground moving DIS targets as input. A prototype of this MTI simulation technique is being developed for incorporation of the Joint STARS radar into a Joint Advanced Distributed Simulation JADS environment. One of the most important performance criteria of an MTI mode is the Probability of Detection Pd of ground moving targets in the presence of clutter assuming a constant false alarm rate. Pd is primarily influenced by the target returns signal-to-noise SN ratio. Another important performance feature influenced by target SN is the location accuracy of the target. This paper develops a method of characterizing target Pd and location accuracy as a function of key radar system variables that can be implemented in the real-time target detection stream of the MTI radar system.
