摘　　要：由于模拟器件的非线性特性,DA产生的波形信号经过了后级的倍频、滤波、放大、混频等模拟器件后,会导致最终输出波形信号幅度及相位失真。为了获得理想压缩特性,研究设计了一种宽带波形校正装置,实现对雷达宽带线性调频信号的失真补偿,该装置通过交互式人机操作界面实现对雷达产品的控制和对信号的自动采样、分析、补偿及数据更新,同时提高了工作效率并降低了人员、设备的成本。The waveform signals output by the DA components are sent to the frequency multipliers,filters,amplifiers,mixers,and other analog components,causing amplitude and phase distortion in the final output waveform signals because of the nonlinear characteristics of analog components.In order to achieve the ideal compression characteristics,a wideband waveform correction device is designed to compensate for the distortion of wideband linear frequency modulated radar signals.The proposed device controls radar and completes automatic sampling,analysis,compensation of signals,and data update through a man-machine interactive operation interface,improving work efficiency and reducing the costs of personnel and equipment.
