摘　　要：在射频仿真系统中,射频目标模拟受到目标模拟阵列视场角的限制,引入倾斜惯性坐标系可以改善这一问题。针对射频仿真系统中由于引入倾斜惯性坐标系带来的实际工程问题,通过剖析问题本质,利用坐标变换推导修正算法,最终得出了相应的目标模拟能力拓展方法。仿真结果表明,该方法能够在不改变末制导雷达的目标检测信息的前提下,通过参数优选有效拓展射频目标模拟范围、提高目标模拟精度,并改善三轴飞行转台姿态模拟性能。In radio frequency simulation system （RFSS）, target simulation is confined to the limit of field viewing angles; gradient inertial coordinate frame （GICF） is effective on the problem. According to the engineering problem of GICF in RFSS, the essence of this problem is discussed, and then the related methods of coordinate transform are analyzed. Finally, the corresponding target simulation enrichment method is proposed. The simulation results indicate that the method can keep the target information of terminal-guided radar unchanged; extend the range and improve the precision of radio target simulation; and enhance the attitude simulation performance.
