Abstract: There exists a fundamental contradiction between achieving large unambiguous sensing range and large maximum unambiguous Doppler measure for traditional pulse-Doppler (PD) radar systems.

Abstract: A uniform pulse repetition interval (PRI) introduces blind ranges due to transmit/receive ($\mathbf{T} \boldsymbol{/} \mathbf{R}$) switching, in addition to range-Doppler ambiguities.
