摘　　要：针对在导弹制导半实物仿真试验中目标模拟能力受阵列视场角范围限制的问题,引入虚拟地面坐标系,将原本与实验室坐标系重合的地面坐标系偏置后进行半实物仿真试验。详细推导了转台姿态和阵列上目标辐射位置的变换方法,给出了地面坐标系偏置角度的确定原则,并针对地面坐标系只在方位上进行旋转的情形进行了讨论。仿真结果表明,应用地面坐标系偏置法可突破阵列视场角范围对目标角位置模拟的限制,有效的拓展了导弹制导半实物仿真系统的目标模拟能力。With regard to the problem that the target simulation ability is limited by the range of array field angle in missile guidance hardware-in-the-loop simulation test,the virtual ground coordinate system is introduced,and the ground coordinate system which coincides with the laboratory coordinate system is rotated and offset to carry out the hardware-in-the-loop simulation test. The transformation method of the attitude of turntable and the radiation position of the target on the array is deduced in detail,and the principle of angle determination of the ground coordinate system offset is given. The situation that the ground coordinate system rotates only in azimuth is also discussed. The simulation results show that the application of the ground coordinate system offset method can break through the limitation of the array field angle to the simulation of the target angular position,and effectively expand the target simulation ability of the missile guidance hardware-in-the-loop simulation system.
