The perception of the radar signal in the frequency domain

摘要

In this paper, two frequency measurement methods of radar signals are presented at first, and then we focus on the introduction of the FFT frequency measurement and its advantages. After that, combining with the characteristics of the radar signal, we introduce a Digital Frequency Measurement structure for the radar signal, which is based on the generous software radio structure. Finally, we discuss about the distributed system for the sensing of the radar signal in the frequency domain.
