| 摘 要： | 针对椭圆球面波函数在窗函数中的应用问题，从能量聚集性角度理论证明了椭圆球面波函数（PSWF）是最佳窗函数，采用基于特征值分解的数值算法求解椭圆球面波函数，筒化了求解过程，算法简便，易于实现。通过仿真分析，与现有的窗函数相比，在相同持续时间和边瓣峰值条件下，椭圆球面波窗函数主瓣最窄、能量聚集性最好，频谱分辨率最高。 |

| Abstract: | For the Prolate Spheroidal Wave Functions(PSWF)applied in window function,it has been proven that PSWF is the best window function from the perspective of energy concentration.Algorithm based on eigenvalue decomposition can provide a simple and flexible numerical solution to PSWF.Compared to the existing window functions,simulation results show that PSWF window function demonstrates the narrowest mainlobe width,best energy concentration and highest spectra resolution at the same pulse time and peak sidelobe... |
