The requirements of a track-while-scan radar data processing scheme are stated from the point of view of the evader in a pursuit-evasion game. The rules of the game, determined in part by the nature of the pursuer's weapons, are such that the evader must be able to discriminate reliably between straight-line and maneuvering pursuer motion. A suggested method for such discrimination is tested by simulation. The method employs bias-sensitive maneuver detection and gain-adaptive discrete Kalman filtering. Also tested is a smoothing scheme for establishing long-term trends in a pursuer's maneuvering track. The outcome of both tests indicate that the suggested processing methods may be useful in the formulation of fire control policies for destruction of maneuvering targets. (Author)
