在分析无线电引信回波信号特点的基础上，提出了用正交调制的方法实现无线电引信目标与背景的多卜勒模拟。在实施的过程中，突破了宽带相乘、宽带90°精密移相、精密合成等技术关键，完成了样机。实验结果表明，该系统工作状态良好，可满足实际使用的要求，具有广泛的应用前景。
Based on the analysis of the characteristics of the radio fuze echo signals, the Doppler simulation of the target and background of the radio fuze is proposed by using orthogonal modulation. In the implementation process, breaking through the broadband multiplication, broadband 90 ° precision phase shift, precision synthesis and other key technologies to complete the prototype. The experimental results show that the system is in good working condition, which can meet the requirements of practical use and has a wide range of application prospects.
