摘　　要：结合有关文献,介绍了传统单脉冲方法的数学原理。研究表明,传统单脉冲和差比幅法实际上是一种搜索方位在和波束最大点附近的单目标的有效方法。此外,详细分析了传统单脉冲在具体工程实现中的相关问题,对多个基本波束半功率点交叉覆盖、单脉冲比的线性特性、直接比幅与和差比幅法的单脉冲比关系、几种差波束口径照射函数的比较等问题进行了理论分析和解释,这些结论有助于加深对传统单脉冲及其改进算法的理解。The mathematical principle of conventional monopulse is introduced directly from the related references. It is shown that sum-difference amplitude-comparison monopulse is in fact an effective search method for a single target with azimuth in the vicinity of the peak the sum beam. Furthermore, the implementation of monopulse in engineering and the related issues are studied. Some theoretical proofs and explanations are provided for overlap at half-power points of basic beams, linear property of monopulse ratio, relationship of monopulse ratio between direct amplitude-comparison method and sum-difference amplitude-comparison method and comparison of several illumination functions for difference beam, which result in an insight into conventional monopulse and its improvements.
