Aiming at the observation constraints of the signal of emitter, a multi-model switching trajectory optimization
algorithm based on dynamic range partitioning is proposed. The algorithm constructs a subinterval partition feature vector
according to the observers in the detectable region to divide the region. Then the corresponding switching strategy is
applied according to different control layer. Meanwhile, this paper designs the movement rules and structures performance
index function based on the switching strategy. According to objective optimization function, the optimization trajectory of
different observer can be obtained by applying a variety of optimization algorithms in the switching sub-layer. Simulation
results show that the method can effectively solve the trajectory optimization problems of the uniform motion target under
the observation constraints, with some engineering application value.
