摘要
多波段 (S、C、X、Ku)数字式陆基雷达散射计系统是一种新型的陆基散射计系统 ,它采用了最新的数字信号处理 (DSP)技术 ,可完成中频搜索、频谱估计、自适应数字滤波等一系列较复杂算法 ,具有测量精度高、速度快等特点 ,再加上其较大的频带覆盖范围 ,是一种可靠实用。
In the design of Digital Ground-based Radar Scatterometer, Digital Signal Processing(DSP) is used to do IF searching, IF estimation, adaptive band-pass filtering, detecting, etc and achieve high measuring speed and accuracy. Four-band scatterometer,which includes S-Band, C-Band, X-Band and Kuband is realized with this method. The system structure, algorithm and the experiment results are introduced in this paper.
