Abstract:
In this paper, the problem of joint optimization of transmit–and-receive Beamforming vectors in array radar is considered. Here, our goal is to maximize the signal-to-interference-plus-noise ratio (SINR) for a point like target in the presence of multiple signal dependent interferences. Therefore, we propose an iterative algorithm, which is based on the convex optimization solution and in each iteration of it, the constrained transmit beamformer is designed by a relaxation and randomization technique. In addition to power constraint, the constant envelop constraint on the transmit beamformer is considered which is important in practice. Simulation results show that the proposed method is able to achieve a higher SINR in comparison with the conventional phased array radar. it is also possible to get close to the performance of non-constrained method by considering the constant envelop constraint.
