  The recently introduced orthogonal time frequency space modulation (OTFSM) is
more robust to large narrow-band Doppler frequency shift than the orthogonal
frequency division multiplexing (OFDM), used in the 5G standard. In this paper
it is shown how the elecommunication OTFSM-based signal with random padding can
be used with success in the 6G standard for detection of high-speed vehicles.
Two approaches for detecting targets during the random padded OTFS based
transmission are compared in the paper
