摘　　要：为了在实验室内进行复合寻的制导系统的性能验证和评估,需要产生模拟射频/红外的复合信号,红外/射频共口径目标模拟器是产生该复合信号的一个关键部件.采用(MOM)和物理光学法(PO)相结合的方法具体分析了红外/射频共口径系统中辐射近场区和远场区电场强度相位分布情况,并对辐射近场区电场强度相位进行了实际测试,两者取得了较好的吻合.在辐射近场区完成了通常情况下天线远场才能实现的目标模拟,大大缩短了测试距离.In order to predict the performance of the hybrid missile-guided system in the indoor condition,the hybrid signal simulator of infrared/RF is needed.The near-field and far-field electrical phase distribution of the infrared/RF co-aperture object simulator is analyzed by using moment method (MOM) and physical optics method (PO).The near-field electrical phase distribution is also measured in the near-field antenna measurement system.The simulated results and measured results are in good agreement.Therefore the long distance far-field measurement can be replaced by the short distance near-field phase measurement.
