An accurate ranging algorithm of symmetrical triangle linear frequency modulation continuous wave radio detector

In this paper, firstly the harmonic ranging fundamentals of the radio detector based on symmetrical triangle linear frequency modulation continuous wave (FMCW) is explained and deduced. Then a series of simulations and analysis of two cases whether the Doppler Effect is concerned or not, is given by utilizing Matlab. An accurate harmonic ranging algorithm of dual-channel amplitude ratio of Doppler signals and amendment of the ratio is proposed and simulated by using Matlab. Results indicate that the algorithm has a good ranging precision.
