中文摘要：

传统的Schmidt方法对椭圆球面波函数（PSWF）脉冲组进行正交化时，脉冲组的最大互相关值受脉冲个数的影响，同时还存在计算复杂度高的问题。针对上述问题，提出了基于Householder变换的正交化方法，通过将PSWF脉冲离散化，再依次对各离散的PSWF脉冲进行Householder变换．买现了对PSWF脉冲组进行QR分解，并得到新的正交PSWF脉冲组。仿真结果表明，与传统Schmidt方法相比，基于Householder变换的正交化方法使得脉冲组的最大互相关值从10^-4降低到10^-11，改善了脉冲组的正交性能，突破了脉冲组在脉冲个数的限制，并降低了计算复杂度，同时能够保持PSWF脉冲带内能量集中度高的优势。

英文摘要：

In using traditional Schmidt method in the orthogonalization of the Prolate Spheroidal Wave Function （PSWF） pulses set, the maximum cross-correlation value of the pulses set is under the influence of pulse number, and this method has a high computational complexity. To solve the problems above, an orthogonalization method based on Householder transformation is presented. The QR decomposition is real-ized through discretizing the pulses set and Householder transformation for the discrete pulse, then the new PSWF orthogonalization pulses set is obtained. Simulation results show that comparing with Schmidt meth-od, the orthogonalization method based on Householder transformation makes the max correlation value re-duced from 10^-4 to 10^-11 and is not restricted to the pulse number, reduces the computational complexity, while maintaining the advantage of high energy concentration.
