摘　　要：分布式网络雷达的多功能承载是目前雷达领域研究的一个热点,基于OFDM信号的雷达通信共享的多功能波形设计受到人们广泛关注,其核心问题之一是较高的包络峰均比(PMEPR)。基于OFDM信号,本文联合自适应限幅门限的迭代限幅滤波技术(AC-ICF)和子载波预留(TR)技术研究了一种面向分布式组网雷达的多功能波形设计方法。首先,建立雷达网络的OFDM信号模型。其次,联合AC-ICF和TR技术研究了低PMEPR的多功能波形设计方法。最后,通过计算机仿真验证了多功能波形设计方法的可行性,并对其中面临的问题进行了分析与讨论,同时对优化设计后波形的雷达和通信性能进行了简要分析。The multi-function carrying capacity of distributed network radar is a hot spot in the field of radar research.The multifunctional waveform design method based on OFDM signal for radar and communication sharing has attracted widespread attention.One of its core problems is the high envelope peak-to-average ratio(PMEPR).Based on OFDM signal,this paper has studied a multi-functional waveform design method for distributed networked radar used adaptive clipping iterative clipping and filtering technique(AC-ICF)and tone reservation(TR)technique.Firstly,we modeled the multi-functional waveform used by the radar network based on the OFDM signal.Secondly,on the basis of the signal model,we studied the waveform design method combining AC-ICF and TR techniques with low PMEPR.Finally,the feasibility of the waveform design method was verified through computer simulation,and the problems faced in it were analyzed and discussed,at the same time,the radar and communication performance of the optimized design waveform are briefly analyzed.
