1. A Radar, comprising;
an interface configured to:
receive a frequency estimation output from a first correlator of a receiver path of a radio communication device, wherein the frequency estimation output is for frequency correction in the receiver path of the radio communication device; and
receive a synchronization signal correlation output from a second correlator of the receiver path of the radio communication device, wherein the synchronization signal correlator output is for timing adjustment in the receiver path of the radio communication device;
wherein the radio communication device is a multi-carrier orthogonal frequency-division multiplexing (OFDM) device, and wherein the synchronization signal is a primary synchronization signal (PSS) of the radio communication device; and
the radar further comprises a processing block configured to use the received frequency estimation output for velocity estimation and to use the synchronization signal correlation output for range estimation.
