With radar cooperative sensing, vehicles can not only leverage their own radar to perceive the road condition ahead but also establish a connection with vehicles in front to obtain environment information farther away. In this paper, a radar cooperative sensing scheme based on multi-hop for vehicular networks is proposed for far-reaching perception. Vehicles on the road perform radar sensing while conducting multi-hop communication with front ones to obtain road information outside the LOS range. In order to streamline hardware equipment and deal with the upcoming shortage of spectrum resources, each vehicle is equipped with TD-JRC to realize both radar sensing and communication function within the same frequency band. Besides, we design a resource allocation strategy for this cooperative sensing system, numerical and simulation results show that there is indeed a optimal joint power and time allocation strategy to realize the maximized average RCSCR for a definite vehicle density.
