摘要
宽带相控阵雷达具有宽带雷达和相控阵雷达的技术优势,通过合成宽带技术可将发射的步进调频信号的回波经由数字信号处理技术合成为宽带信号,从而得到探测目标的高分辨距离像。论文基于步进调频信号的回波模型,讨论了频域带宽合成处理方法,最后通过仿真实验,对比了直接发射线性调频信号与频域带宽合成法所成的距离像,并对仿真结果进行了分析,从而验证了此方法的有效性。
Wideband phased array radar has the technical advantages of wideband radar and phased array radar. The bandwidth synthesis technique can synthesize the echo of the transmitted Chirp-SF signal into a wideband signal through digital signal processing technology,thus the high resolution range profile of the detection target is obtained. In this paper,based on the echo model of Chirp-SF signal,the frequency domain bandwidth synthesis processing method is discussed. Finally,the range profile formed by the direct transmission chirp signal and the frequency domain bandwidth synthesis method is compared by simulation experiments,and the simulation results are compared. The effectiveness of this method is verified.
