| 摘 要： | 对于反辐射雷达导引头,较宽的波束导致多个目标辐射信号进入导引头接收系统,所以必须提高其多源测向和多目标分辨能力.为此,提出采用超分辨测向技术来估计多个辐射源的到达角,并对该方法的可行性进行研究.首先,给出反辐射导引头超分辨测向模型,在此基础上,采用MUSIC算法进行到达角估计,并对影响MUSIC算法估计精度的因素进行了...

| Abstract: | For anti-radiation seeker with larger beamwidth,the signal from multi-sources will enter seeker＇ s receiver simultaneously. It is necessary to improve the capability of multi-sources direction finding and multi- targets resolving. For this purpose, the high resolution direction finding technique is adopted to estimate targets direction-of-arrival（DOA）, and it＇s feasibility is studied. The seeker model for high resolution direction finding is given. On this basis,MUSIC algorithm is introduced to estimate targets DOA. And simulating and perform- ance analyzing of MUSIC algorithm are done. The results show that the method can realize multi-sources direction finding. |
