| | This paper describes a FFT method of signal processing for an FMCW detec-tion radar. Based upon this method. Some experiment results on the model of a metal sheet and a plastic pipe buried in the- building are given. The results show that the FFT method is and effective way for the FMCW detection radar in signal processing. | | 本文给出了应用于调频连续波(FMCW)探测雷达数字信号处理中的快速傅里叶变换(FFT)方法,并在此基础上给出了针对以建筑物墙中埋藏的金属板和塑料管为探测目标模型的实验结果.该结果表明,快速傅里叶变换(FFT)方法是对探测雷达系统的回波信号进行数字信号处理的有效方法. | | 文摘来源 | | Abstract A kind of Radar Moving Target Detection (MTD) ASIC has been designed. The iC adopted the Finite Impulse Response (FIR) filter structure composedof ping-pong RAM and pipelined multiplier has the advantages of high speed, simplestructure and so on. It is proved by logic and circuit simulatioD that the iC has'good performance. | | 本文设计出一种用于雷达数字信号处理的动目标检测(MTD)专用集成电路.该电路采用有限冲激响应(FIR)滤波器结构,并配以乒乓存储器及流水线乘法器,具有运算速度快、结构简单等优点.经逻辑和电路模拟,证明该电路具有良好性能. | | 文摘来源 | | This article states the principle and composition of the high speed analog-to- digital converter AD9058. It also gives a applied example in radar digital signal processing system, the consideration of both the design and the making for a A/D converter involved. | | 介绍了 AD9058的原理、结构,讨论了基于 AD9058的高速 A/D转换器的设计,给出了其在雷达数字信号处理系统的应用实例。 | | 文摘来源 | |   | | << 更多相关文摘 |
