1. A radar system, comprising:
a transmitter configured to:
provide a code comprising a first gap at a beginning, a second gap at an end, a cyclic prefix, an N chips segment following the cyclic prefix, and a training sequence;
identify a plurality of regions within the code based on the cyclic prefix and the N chips segment;
apply a transmitter-specific cyclic shift scheme to the plurality of regions;
generate a signal from the code and transmit the signal; and
a receiver, configured to:
receive an echo of the signal; and
identify the transmitter based on the transmitter-specific cyclic shift scheme.
