摘要

双功能雷达通信（DFRC

dual-function radar-communication）技术利用相同的硬件平台、频谱资源和发射波形同时实现雷达和通信功能，为实现通信感知一体化功能提供强有力的支撑。针对双功能雷达通信系统，研究了雷达和通信的波形折中优化设计，同时考虑在传输能耗和峰均比约束下，构建具有二次等式和不等式约束的非凸优化问题，并利用非线性等式约束交替方向乘子算法将非凸优化问题分解为3个子问题实现优化求解。仿真结果表明，优化设计的双功能雷达通信波形可逼近理想雷达波形，同时实现了雷达性能和通信性能之间的折中优化。

Abstract

Based on the same hardware platform

spectrum resources

and transmit waveforms

dual-function radar-communication (DFRC) can achieve radar and communication functions at the same time

which provides a strong support for realizing integrated sensing and communication (ISAC).Aiming at the dual-function radar communication system

radar and communication waveform trade off optimal design was studied

and a non-convex optimization problem was constructed with quadratic equality and inequality constraints under the constraints of transmission energy consumption and peak-to-average ratio (PAPR).The nonlinear equality constrained alternative direction method of multipliers was used to decompose the non-convex optimization problem into three sub-problems.The simulation results show that the optimized dual-function radar communication waveform can approach the ideal radar waveform and realize the optimal performance tradeoff between radar and communication.
