  • Noise Frequency Modulated Continuous Wave (FMCW) radar has an ideal thumbtack ambiguity function, and unambiguous measurement of distance and velocity due to the nonperiodicity of its transmitting signal, so it is suitable for detecting high-speed and long-distance targets on orbit in principle. The high speed moving targets echo signals of Noise FMCW are generated by interpolation in this paper. An approach to improve the main-to-sidelobe ratio by utilizing Matched reference signal to correct the range migration in Noise FMCW and single frequency combined radar system is presented. The FFT-IFFT technique and Clean method are used to enlarge the dynamic range. Simulation results verify the effectiveness of this new method.
