ISAC Device-Free Sensing Method for V2V System

With the development of information technology, integrated sensing and communication (ISAC) can be directly used in the vehicle-to-vehicle (V2V) scenarios. Since the ISAC system can reduce the communication overhead and realize the device-free localization of vehicles in noncooperative scenarios. A novel passive vehicle location method combines the Doppler time-sharing and the Barker code is proposed in this paper. By using the proposed method suppress the clutter interference, the target vehicles can be accurately located separately. The simulation results show that we can finally realize the accurate perception of 6 vehicles within a kilometer range.
