摘要
考虑了雷达成像中的一个波形设计问题.基于匹配滤波,在Sobolev空间的框架下,使用Hermite多项式理论,并通过一种数值算法,实现了波形的优化设计.数值实验表明,该方法是有效的.相比于CW(continuous wave)脉冲和线性调频脉冲方法,该方法可以得到更高的分辨率.
A problem of waveform design in radar imaging is considered. Based on the matched filter, an optimal design of waveform is realized by a numerical method in which the theory of the Sobolev space and the Hermite polynomial are used. Numerical experiments have shown effectiveness of this method. Compared to the CW （continuous wave） pulse and the chirp pulse, this method gives better resolution.
