“…Studies show that although these models have reasonable real-time performance, they have some inherent drawbacks such as the lack of characterization of innate dynamics and inability to consider the nonlinearity of the dynamics. In order to develop new dynamic models, the concept of maneuvering coefficients was introduced to describe the motion of a maneuvering missile [13]. Then the state augmentation method was adopted to estimate the ballistic and maneuvering coefficients [14].…”

“…An interested reader can see Dwivedi et al. 19 for more details about target estimation, which is not the focus of this paper.…”

“…Note that in reality there has to be good target estimation logic in the loop to estimate the target trajectory as well as its ballistic coefficient. An interested reader can see Dwivedi et al 19 for more details about target estimation, which is not the focus of this paper.…”
