摘要/Abstract

摘要：

全数字阵多输入多输出（multiple input multiple output, MIMO）雷达当阵元数较多时成本显著增加，采用子阵MIMO雷达可降低系统成本并同时发挥MIMO雷达自由度多的优势，但相应的波形优化理论研究较少。针对子阵MIMO雷达波形优化设计，提出脉压宽主瓣结合收发联合设计算法，以系统整体能力为约束进行波形优化设计，分别研究相控阵场景、发射方向图单峰和双峰3种情况下的波形优化准则。仿真实验表明，脉压宽主瓣技术结合收发联合设计的子阵MIMO雷达一体化波形设计算法提升了雷达波形自由度，使全局峰值旁瓣电平下降4.88~6.54 dB，并使雷达发射波束具有多峰匹配能力，达到了预期设计效果。

Abstract:

Fully digital array multiple input multiple output (MIMO) radar face significant cost challenges when the number of array elements is large. Employing a subarray MIMO architecture can effectively reduce system costs while retaining the high degrees of freedom inherent in MIMO radar. However, corresponding research on waveform optimization theory for this architecture remains relatively scarce. For subarray MIMO radar waveform optimization, this paper proposes a joint design algorithm integrating pulse compression wide mainlobe technique and transceiver co-optimization. The waveform optimization design is constrained by the overall system capability, and the waveform optimization criteria are studied under three scenarios: phased array, mono-peak, and dual-peak transmit beampattern. Simulation results demonstrate that the integrated waveform design algorithm combining pulse compression wide mainlobe with joint transceiver design improves waveform degrees of freedom, reduces the global peak sidelobe level by 4.88?6.54 dB, and endows the transmitted beam with multi-peak matching capability. The intended design effect is achieved.

Key words: subarray multiple-input multiple-output (MIMO) radar, waveform optimization, pulse compression wide mainlobe technology, joint transmit receive design
