Description

technical field [0001] The invention relates to the technical field of precision guidance, in particular to a single-platform multi-sensor information fusion processor and an experiment system. Background technique [0002] With the increasingly complex combat environment of the modern battlefield, it is becoming more and more difficult for single-homing mode guided munitions to complete tasks. Multi-mode compound guided precision-guided munitions are becoming the focus of development in various countries. At present, there are many models at home and abroad. Advanced compound guided munitions are equipped with armies of various countries. The related information fusion processing algorithm is also developing rapidly, but the effect of the algorithm is only limited to theoretical simulation, and the actual application needs further verification. The algorithm of the guidance system has high requirements for real-time performance, and the pure digital simulation of the compu...
