Radar Sensing with OTFS: Embracing ISI and ICI to Surpass the Ambiguity Barrier
Radar Sensing with OTFS: Embracing ISI and ICI to Surpass the Ambiguity Barrier
Orthogonal time frequency space (OTFS) is a promising alternative to orthogonal frequency division multiplexing (OFDM) in high-mobility beyond 5G communications. In this paper, we consider the problem of radar sensing with OTFS joint radar-communications waveform and derive a novel OTFS radar signal model by explicitly taking into account the inter- …
