摘　　要：针对雷达通信一体化(DFRC)系统中,波形设计求解算法复杂度高的问题,提出了一种基于Gurobi的低复杂度求解方案.首先,构建了DFRC系统模型,将波形的总功率和与参考雷达信号的相似性作为约束条件,将最小化下行多用户干扰(MUI)能量作为优化目标.然后,运用Gurobi优化求解器对上述非凸二次约束二次规划问题进行求解.最后,通过权重因子对DFRC系统的通信和雷达性能进行了权衡设计.仿真结果表明,在相同信噪比条件下,本文方法相比奇异值分解(SVD)方法的总传输速率提高了75%,复杂度有明显降低,能够实现DFRC系统在进行用户间通信的同时探测目标的功能.In order to solve the problem of high complexity of waveform design algorithm in Dual-Functional Radar-Communication(DFRC)system,a low complexity solution based on Gurobi is proposed.Firstly,a DFRC system model is constructed,with the total power of the waveform and the similarity to the reference radar signal as constraints and the downstream Multi-User Interference(MUI)energy minimized as the optimization goal.Then,optimization solver Gurobi is used to solve the above non-convex quadratic constrained quadratic programming problem.Finally,the communication and radar performance of the DFRC system are given a tradeoff design through weight factors.Simulation results show that under the same signal-to-noise ratio condition,the total transmission rate of the proposed method is 75%higher than that of singular value decomposition(SVD)method,with a significant reduction in complexity,and that the proposed method can achieve the function of communicating between users while detecting targets.
