| 摘 要： | 突破宽带信号数字生成方法的框架 ,提出了基于波形存储和实时计算相结合的调频步进雷达回波高速实时数字生成新方法。基于某调频步进雷达系统的研究 ,提出的解决方案摆脱了传统的波形存储直读法和直接数字合成法的局限性 ,即不适应于变换参数的情况 (比如运动目标 ) ,成功地实现了运动多散射点目标回波的实时产生 ,证明方案可行。还对算法的数值稳定性进行了分析。

| Abstract: | Based on a wide hand radar's design,this paper presents a modulated step frequency radar waveform processing method ,and puts forward a high speed real time digital generation method based on SHARC,which is derived of signal subsection decomposition and iteration.The paper exceeds the limit of traditional wide band signal's digital generation,which is mainly based on two digital methods,direct wave access and direct digital synthesis,but they don't adapt to the variational parameters' system( such as moving target processing).The arithmetic's numeric stability is analyzed.Experiments prove this resolution is feasible. |
