摘　　要：在介绍了国外反辐射无人机导引装置幅相联合测向技术的基础上,分别就干涉仪、比幅法测向条件下导引装置测向性能进行了仿真分析。结果表明,导引装置采用干涉仪测向时精度较比幅法测向的精度高,但存在测向模糊;比幅法测向精度不高,但可以解除干涉仪测向产生的模糊。最后,分析给出了测角范围与目标雷达频率、测角误差与测量到达角的关系,得出了导引装置采用幅相联合测向的优势。On the base of analyzing the direction finding combined amplitude and phase of a certain anti-radiation unmanned aerial vehicle（ARUAV）seeker, the direction finding performance of the seeker indirection finding with interferometer and amplitude comparison is simulated and analyzed separately. The results show that, the accuracy of direction finding with interferometer which contain ambiguity is higher than with amplitude comparison which can release fuzzy. Finally, the relationship between the range of the measuring angle and radar frequency, angle error and angle of arrival is given. And the advantage of direction finding combined amplitude and phase which seeker adopts is educed.
