Abstract:To solve the problem caused by multi-target interference in the terminal guidance phase, which affects stable target tracking and results in the final miss, the influence of multitarget interference on the seeker’s angle tracking is analyzed, and multi-target interference compensation methodology using multiple output angle error equations with different detection frequencies at single sensing period to extract the unknown parameters of multi-target interference based on the orthogonal multicarrier technique is proposed in this paper. The method is verified reasonable and feasible through the simulation analysis, and the analysis result can be applied to improve the tracking precision of the seeker’s terminal guidance phase.
