Abstract:

The calculation of jamming time is the prerequisite and basis for making jamming decision. Firstly, two schemes are designed after analyzing the problem. Secondly, in order to realize an air fighter’s optimal flying control planning, the flying capability, threat constraints and flying border constraints are considered, based on which the optimal path control model is built. Thirdly, by introducing a Legendre pseudospectral method (LPM) which is mainly used in spaceflight control field, the optimal control problem is transformed into a nonlinear programming(NLP) problem, and then the calculating flow of the jamming time is designed. Fourthly, through improving the c code feasible sequential quadratic programming (CFSQP) algorithm, the optimal results of the NLP problem can be quickly searched. Finally, simulation studies show that the scheme can get the optimal start and end time of jamming.
