“…When the delay time of target echo is greater than the repetition period of transmitted pulses, range ambiguity will occur [4][5][6]. In addition, when the Doppler frequency caused by target motion is greater than half of the repetition frequency of the transmitted pulse, velocity ambiguity will happen [7].…”

“…The method is free from restriction related to the maximum center-frequency separation between utilized sub-bands, but does not rely on the FT, making its latency unpredictable since it relies on algorithm convergence. An interesting approach which unbinds the Doppler ambiguity interval from the PRF is presented in [11], but requires the usage of time-shifted opposite-slope chirps, and is iterative along target-peaks, making it unsuitable for extended meteorological targets like rain. The method in [12] decouples the maximum range from the Doppler velocity interval by processing received signals in overlapping sections of two sweeps (using a synthetically stored chirp).…”

“…There usually is a practical limit to how much will extrapolated data really represent target returns as associated with their Radar-Cross-Section (RCS). The work in [10] uses waveform diversity to decouple the Doppler cycle from the PRF, but does not address range resolution improvement. We proposed the extrapolation and linking of parts of beat frequencies -within the same sweep -in the STFT domain for the purpose of interference mitigation in [11].…”
