摘要
Abstract
The integrated waveform of radar interference based on OFDM architecture is a hot research topic in re-cent years.This type of waveform separates the detection subcarriers from the interference subcarriers,and has the struc-tural characteristics of stable detection subcarriers and flexible interference subcarriers which can ensure both the detec-tion and interference performance of the waveform.Besides,this waveform has the characteristic of relatively large PA-PR.This article proposes a precoding-TR joint PAPR suppression algorithm for the modulation characteristics of this waveform subcarrier.The algorithm combines the principles of precoding PAPR suppression algorithm with TR PAPR suppression algorithm,and can effectively constrain the waveform PAPR while maintaining the energy allocation method of the integrated waveform detection and interference subcarrier unchanged.Theoretical and simulation experiments show that the precoding-TR joint PAPR suppression algorithm proposed in the article has the performance advantages of no distortion,strong PAPR suppression ability,high efficiency and stable performance for integrated waveforms.关键词
