摘要
线性调频连续波信号是随钻雷达常采用的信号形式。从理论上分析了线性调频连续波随钻雷达的工作原理及实现方法;利用快速傅立叶变换(FFT)处理技术对线性调频连续波随钻雷达的回波信号进行了信息提取。仿真结果验证了理论分析的正确性和实现方法的可行性。
Radar-while-drilling is playing an important role in ensuring drilling safety.Linear frequency modula-tion continuous wave（LFMCW） signal is usually used by radar-while-drilling.The paper analyzes working princi-ple and realization method of LFMCW radar-while-drilling theoretically,and then the information extraction of target echoes of LFMCW radar-while-drilling is achieved by using fast Fourier transform（FFT） technique.The simulation result verifies the correctness of theoretical analysis and feasibility of implementation method.
