An orbital three-player conflict with impulsive thrust is studied in this work. Due to the absence of maneuver capabilities of the target spacecraft, a defender spacecraft is engaged to eliminate the threat of the attacker spacecraft to the target spacecraft. The orbital three-player conflict is divided into two layers. In the internal layer, the attacker spacecraft tries to intercept the target spacecraft,...
An orbital three-player differential game among Target spacecraft, Pursuer spacecraft and Evader spacecraft is studied in this work. It is assumed that Target spacecraft runs in its orbit without the ability of maneuver, while Pursuer spacecraft and Evader spacecraft have continuous maneuverability. There are opposing objectives between Pursuer spacecraft and Evader spacecraft. The objective of Pursuer...
In this paper, an enhanced one-bit-transform-based region of interest (ROI) method is proposed for the infrared small target detection under complex background. This novel method, named as En1BT for short, leverages the local variance weighted information entropy filter to increase the signal-to-noise ratio (SNR), followed by the one-bit transform method to automatically compute a valid threshold...
This paper presents an improved method for trajectory planning of mobile robot in random obstacle environments. A combination of first local then global path planning is used in the real-time planning system modeling. The global path planning method adopting target direction angle tracking strategy is formulated. The local trajectory planning method is implemented by a quantum-behaved particle swarm...
