本文以连续波多普勒无线电引信为研究背景，建立目标信号数学模型，针对目前炸高控制方法及存在问题，提出了一种新的多普勒脉宽技术测高方法，在此基础上增加一个近表面炸的性能。并介绍了采用可编程逻辑器件实现的方法以及计算机仿真。实践证明，对 Ｄｏｐｐｌｅｒ信号的数字信息处理，用一片 ＣＰＬＤ实现，提高引信信号处理的速度，并极大提高了系统的可靠性。
In this paper, continuous wave Doppler radio fuze is taken as the research background, the mathematical model of the target signal is established, a new Doppler pulse width technology altimetry method is proposed in view of the current explosion height control method and existing problems, on the basis of which a Near surface fried performance. The method of using programmable logic device and the computer simulation are also introduced. Practice has proved that the Doppler signal digital information processing, with a CPLD to achieve to improve the speed of signal processing fuze and greatly improve the reliability of the system.
