High Speed Space Targets Detection Using Noise Frequency Modulation and Single Frequency Combined

摘要

摘要: 噪声调频连续波雷达由于发射信号无周期，具有理想的图钉型模糊函数，没有周期性距离模糊和速度模糊，从原理上非常适合在轨探测远距离的超高速空间目标。该文采用插值法建立了噪声调频连续波高速目标回波模型，提出噪声调频复合单频连续波雷达采用校正距离走动的匹配参考信号进行相参处理的方法，实现跨距离门积累从而提高距离主旁瓣比；针对多个目标的检测采用FFT-IFFT逐个Clean的办法，进一步提高检测目标动态范围。仿真结果表明所提出的方法是有效可行的。

Abstract: 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.
