Abstract

A practically-realizable micro-Doppler experiment is designed, conducted, and demonstrated. The cost-effective experimental setup is composed of common signal generator, spectrum analyzer, transmitting and receiving antennas, and a metallic rod rotated via a driving stepper motor to induce micro-Doppler effect. For providing different micro- Doppler features, different revolution per minute (RPM) of the rod can be chosen and adjusted. The operating frequency is chosen in S band for long-range radar applications. To consider the demand of real-time computation for national defense purpose, two fast computed algorithms to correctly extract the micro-Doppler feature of a scattered target are proposed and illustrated by clear physical insight. The micro-Doppler effect of cross-polarized scattered signal is also investigated and the effectiveness and robustness of the proposed algorithms are further verified. The experimental result shows that the deviation between theory and measurement is not more than 1 %.
