| description | Abstract This letter presents a new method of focused energy delivery (FED) with low grating lobes for precision electronic warfare (PREW). The transmitted signal model is modified by equipping each platform with a linear uniform antenna array, enabling the same performance with lower power and providing a greater degree of freedom in the design of the transmitted signals than traditional methods. Moreover, the L∞‐norm is considered as a regularization term in the model to simultaneously realize FED and alleviate the grating lobes. To solve the nonconvex NP‐hard multiobjective optimization problem (MOP), block coordinate descent (BCD) is employed to separate the problem into two subproblems with respect to the amplitude and phase components of the signals. Then, these two subproblems are solved using Taylor expansion (TE) and the alternating direction penalty method (ADPM), respectively. Simulation results demonstrate that the proposed method exhibits superior performance compared to previous methods. |
