| Abstract: | 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. |
