针对相干多输入多输出（MIMO）雷达，研究了低采样处理策略下的相位编码线性调频连续波（PC-FMCW）波形。PC-FMCW MIMO结构，它联合使用快时间和慢时间编码，提出了降低旁瓣电平，同时保持高距离分辨率，明确的速度，良好的多普勒容限，和低采样需求。对PC-FMCW MIMO结构的传感性能和实用性进行了理论分析和实验验证。数值仿真和实验表明，该MIMO系统保持了线性调频连续波（LFMCW）波形的优点，包括计算效率和低采样要求，同时具有同时传输的低副瓣水平的能力。
The phase-coded linear-frequency-modulated continuous-wave (PC-FMCW) waveform with a low sampling processing strategy is studied for coherent multiple-input multiple-output (MIMO) radar. The PC-FMCW MIMO structure, which jointly uses both fast-time and slow-time coding, is proposed to reduce sidelobe levels while preserving high range resolution, unambiguous velocity, good Doppler tolerance, and low sampling needs. The sensing performance and practical aspects of the introduced PC-FMCW MIMO structure are evaluated theoretically and verified experimentally. The numerical simulations and experiments demonstrate that the proposed MIMO keeps the advantages of the linear-frequency-modulated continuous-wave (LFMCW) waveform, including computational efficiency and low sampling demands, while having the ability to provide low sidelobe levels with simultaneous transmission.
