【Abstract】 Random perturbation errors during the launching process of space tethered-nets are systematically analyzed to evaluate their impact on target capture. Stochastic process models and error distribution models are established to characterize the random errors. Criteria for successful capture of space tethered-nets are proposed, and a capture probability model under error superposition conditions is constructed using the Monte Carlo method. The optimal capture range for square space tethered-nets is analyzed. Numerical simulation results reveal that random perturbation errors cause displacement of the net surface center point and reduce the unfolding rate. Under ideal conditions, the capture range is broader, while error superposition significantly narrows the optimal capture range. These effects substantially impact the capture capability and range of space tethered-nets. The established error distribution model and capture probability model provide critical theoretical foundations for optimizing and designing launch parameters of space tethered-nets.更多还原
