Vector Field Based Guidance Law for Intercepting Maneuvering Target

摘要

A vector field based guidance law for intercepting maneuvering target is proposed. The vector field based guidance laws are easy to implement and show high accuracy in a path following problems. To adopt the vector field based guidance law for the missile system, target interception problem is considered as path following problems. After modeling the predicted target trajectory as an implicit function, a vector field is calculated to make missile converge to the predicted target trajectory. The performance of the proposed guidance law is demonstrated by numerical simulations comparing the interception performance with that of proportional navigation guidance laws. The vector field based guidance law shows high interception accuracy (small miss distance) and accomplishes ideal head-on interception.
