摘要
用Walsh归一化函数法描述高频地波雷达海面Bragg散射原理的物理过程简单、清晰并广为接受。概述Walsh归一化函数法的基本原理以及利用该方法获取高频雷达单基地、双基地脉冲和调频连续波(FMCW)波形截面图、一阶Bragg尖峰随机扰动分析等方面的主要成果,指出这些成果的主要应用场景和优势,并对进一步研究、开发的前景予以简单介绍。
Abstract
Walsh’s generalized function method has illuminated its concision and distinction in the description of the Bragg scatter mechanism and been well accepted around the world in the field of High Frequency(HF) electromagnetic wave scattering over the ocean surface. The foundation theory of the generalized function method is outlined. The first-and second-order HF radar cross sections are depicted with monostatic and bistatic operations, along with the pulsed and Frequency Modulated Continuous Wave(FMCW) radar waveforms. Some front edge results are discussed, such as the statistical properties of the first-order Bragg fluctuations with their possible applications and superiority in solving the practical problems. The prospect of further research and development is pointed out as well.
