Abstract
In the measuring system of modern shooting ranges, numerical differentiation, which is key to the process of external ballistic measurement determination of carrier rockets, must be adopted for calculating kinematic velocity and acceleration parameters of carrier rockets by means of optical and radar measurement data. As existing numerical differentiation is not steady enough, the loss function is improved by fitting differential algorithm and this paper establishes a new steady fault-tolerant numerical differentiation with relatively high accuracy and fault-tolerant ability, so as to improve and enrich high-accuracy external ballistic measurement computing technology. The simulation results show that new numerical differentiation technique has high accuracy and practical engineering value.
