During the hardware-in-the-loop simulation of multimode compound guidance, it is common for the receiving antenna center to deviate from the rotation center of the turntable. In this regard, this paper proposes a method for dynamic target simulation of non-coplanar multimode radar. The corrected position of the target simulation at any receiving antenna center position and any target theoretical position is derived through the spatial geometric relationship. Aiming at the situation where the target position after correction is outside the original triad of antenna array, the target localization vector control method of the triad of antenna array at any observation position is proposed. Using this method as a criterion for pros and cons, the particle swarm optimization algorithm can be used to simulate targets at any location. The error between the expected angles and the corrected angles is within 0.02° according to the digital simulation. This accuracy can satisfy the dynamic target simulation requirement in the hardware-in-the-loop simulation.
