Abstract

In this paper we introduce the principle of the monocular ranging algorithm based on constraints on trajectory and line of sight, focusing on the long-distance detection for moving point targets. Simulations and experiments based on the proposed algorithm are carried out, in which the various factors related to the performance are analyzed. The results show that the improved algorithm is more suitable for long-distance air-to-air detection than traditional methods. As for the accuracy in the long ranging detecting situations, increasing the measurement time and the acceleration of the flying platform can improve the ranging accuracy. Furthermore, enhancing the angle measurement accuracy of the optical components can effectively improve the ranging accuracy.
