In this paper, transmit beamforming and power control of active phased array radars is deployed to reduce probability of interception. With assumption, that the position of the interceptor is known using the information obtained from electronic support measure systems. Effective radiated power of radar in taegt and interceptor directions analysed. To reduction of interception probability, the effective radiated power in the interceptor’s direction is managed while desired radar detection performance is guaranteed and the power budget of each T/R module is satisfied. Beamforming weights are analytically optimized based on a convex optimization framework. Two proposed beamforming designs are compared with the standard Log-Barrier method in terms of interception The results show that the performance of the proposed algorithms is equal to the results obtained from the CVX software package and it performs better than the benchmark Log_Barrier algorithm in terms of the probability of eavesdropping and in terms of computational complexity.
probability and convergence time.
