为了保证宽带阵列通道间的幅相一致性，通常需要加入校正滤波器。通道校正的性能与滤波器的系数和结构有关。该文从校正的效果和实时性两方面出发，分别提出了奇异值分解法和改进的带宽分割法。前者用于保证最小二乘求逆时解的稳定性，增强校正性能；后者采用并行处理的方法满足实时性处理要求。仿真结果表明，两种方法都能提高校正性能，在实际工程应用中，可以根据实时性和硬件复杂度等要求进行选择。

A calibration filter is usually needed to ensure the broadband array channel amplitude phase consistency. The performance of channel calibration is affected by the filter's coefficients and structure. Considering effects and the real-time of calibration, the singular value decomposition ( SVD) method and the improved band segmentation method are presented here. The SVD ensures the solution stability and enhances the calibration performance. For the improved band segmentation method,the parallel processing is adopted to meet the real-time processing requirements. Simulation results show that both methods can improve the calibration performance. They can be chosed according to the performance requirements of the real-time and the hardware complexity.
