An interference mitigation technique for FMCW radar using beat-frequencies interpolation in the STFT domain. Coherent waves are waves that have the same frequency and waveform. Why is sending so few tanks Ukraine considered significant? An interference pattern is formed using yellow light passing through a pair of narrow slits. These interference phenomena decrease for impure samples as a result of the incoherent forbidden scattering induced by the impurities. The total received signal can be considered as the sum of the target signal and the interfering signal, that is, Interference envelope detection is the first priority in interference mitigation.
