Many vehicular spread spectrum (SS) radar systems for inter-vehicles communication and ranging have been proposed. It is possible to communicate and measure the distance between the user and targets, the relative speed, and the angle to multiple targets and to communicate with the multiple targets by the vehicular spread spectrum radar system. However, if multiple targets exist at different places with the same distance from the vehicle, it is difficult to separate the signals by identifying the targets. In this paper, we apply the algorithm of detecting different direction of arrivals (DOAs) of the reflected signal waves from the targets, which is based on the spatial spectral estimation capability of an array antenna. Performance of the proposed schemes is analyzed by computer simulations.
