| Abstract: | Moving targets detection by LFMCW has always been a tough issue. Moving targets can be effectively detected and examined and unchangeable clutter can be restrained by extracting information from target echoes using two-dimensional FFT techniques. In this paper, analysis and simulation are carried out over the beat frequency phase that has been deduced. Its further applications are discussed and the algorithm complexity analyzed. |
