For pulse compression, stretch processing offers a low sampling rate, computationally simple alternative to the conventional matched-filter-based approach for radar/sonar receivers to pulse-compress the linear frequency modulated (a.k.a. chirp, linear chirp, or sweep signal) radar returns. A question remains in the open literature whether this stretch processing method could be applied to other constant-modulus polynomial-phase modulations. A concise mathematical proof is presented to show the answer as no; the linear frequency modulation (LFM) is the only constant-modulus polynomial-phase-based pulse compression suitable for stretch processing.
