| 摘要: |
| 针对极化敏感阵列在工程应用中所受到的诸多限制条件，本文提出了一种新型交替极化阵列结构，分析了其在滤波抗干扰中的理论极限性能，并与极化敏感阵列滤波性能进行对比研究。研究表明：相对而言，交替极化阵列在设备量减半、信号处理自由度减半的条件下，滤波抗干扰性能逼近极化敏感阵列，克服了极化敏感阵列系统复杂性带来的一系列问题，因此在阵列雷达领域具有广泛的应用前景。 |

| Abstract: |
| Considering the conditionality of the Polarization Sensitive Array (PSA) in realization, an original Alternate Polarization Array (APA) is proposed. The ultimate filtering performance is presented theoretically and numerically, which is contrasted with that of PSA comprehensively. Compared with the PSA, the filtering performance of APS approaches that of PSA, but the equipments and the degree of freedom is cut by half. The APA overcomes the disadvantages in implementation of PSA. Therefore, APA has great potential to be used in arrayed radar and other fields. |
