In this paper, we propose a transmit-receiver alternating minimization (TR-AltMin) algorithm for integrated sensing and communication (ISAC) systems in vehicular ad-hoc networks (VANETs) with hybrid analog-digital (HAD) beamforming structure. Given the ideal beamformer for radar and the channel information for communication, consider the minimum beamformer error for radar and the minimum mean square error (MMSE) or weighted MMSE (WMMSE) metric for communication, a weighted summation optimization problem is obtained, and the TR-AltMin algorithm is used to get the optimal results of the HAD beamformer and combiner. Numerical simulation results show that the proposed method has better performance in terms of the communication-radar (C-R) trade-off and C-R functionalities.
