本文论述了脉冲多卜勒体制与单脉冲体制的蒹容性问题。分析了当两者结合,特别是采用数字信号处理时,所带来的一些原理性的和工程性的问题。依据分析,给出了解决这些问题的机载脉冲多卜勒单脉冲角信息提取的数字处理方案。与现有的处理方案相比,它具有角跟踪精度高、抗干扰性强、工作稳定可靠、有无源角跟踪能力、误差调制频率不受限制以及系统动态范围要求低、设备简单等重大优点。
This paper discusses the problem of pulse Doppler system and single pulse system. Analyzed the combination of the two, especially when using digital signal processing, some of the problems caused by the principle and engineering. Based on the analysis, the digital processing scheme of Doppler single pulse angle information extraction of airborne impulses is given to solve these problems. Compared with the existing processing scheme, it has many advantages such as high accuracy of tracking, high anti-interference, stable and reliable operation, passive angular tracking capability, unlimited error modulation frequency, low system dynamic range requirement and simple equipment .
