| 摘要: |
| 联合空时抗干扰方法，性能优于单纯的空域或单纯的时域抗干扰，但是由于其计算复杂度大，实际应用受到一定限制。针对这一矛盾，在MSNWF基础上，通过分析抗干扰天线阵观测信号协方差矩阵的Toeplitz特性，构造高维Toeplitz矩阵，利用FFT技术，提出一种联合空时抗干扰天线阵的快速实现方法。计算量的比较结果表明该方法可以大大降低STAP的计算量，使得联合空时抗干扰技术的实际应用变得更容易。 |

| Abstract: |
| Joint Space-time Anti-jamming technique has better performance than both space domain processing and time domain processing, but its implementation is difficult due to its computational complexity. With the toeplitz feature of the observation covariance matrix, the covariance matrix to a big toeplitz matrix can be expanded. Based on the new toeplitz matrix and the FFT technique, a fast implementation approach of MSNWF was proposed for joint space-time processing. The comparison result of computation consumption shows that the new approach is efficient, making it easier for the application of joint space-time anti-jamming technique. |
