Abstract:

This paper investigates the processing of delay and Doppler information with IEEE 802.11p OFDM signaling for multi-target detection. We study the feasibility of extending IEEE 802.11p short-range communication (DSRC) in vehicles to automotive radio detection and ranging (radar) functionality. By exploiting the unique structure of 802.11p OFDM packets over multiple subcarriers and multiple time-slots, we apply the estimation of signal parameters via rotational invariance technique (ESPRIT) for concurrent multi-target detection and range/velocity estimation. Numerical results show sub0.2 m accuracy in range estimation and sub-0.02 m/s accuracy in velocity estimation with high probability.
