A BALLISTIC ANALYSIS SYSTEM BASED ON DIGITAL SPECTRUM ANALYSIS

测速雷达是武器试验中一种不可缺少的基本设备,新型武器的研制和开发对其性能提出了越来越高的要求。基于数字频谱分析技术的新型测速雷达,采用频城测速方法来提取目标的速度信息,与传统的测速雷达相比,性能有了很大提高。它不仅能有效地增加雷达的作用距离,还可增加多目标检测和弹丸转速测量等功能。本文将阐明频域测速的原理和实现过程,介绍一种基于该原理的弹道分析系统的组成和功能,并给出有关的实验结果。

The radar for velocity measurement is a fundamental equipement in a weapon test base and must have highest performance to satisfy the needs of research and development of new weapons and ammuniations. A new radar for velocity measurement based on digital spectrum analysis uses the method of velocity measurement in frequency domain and has better performance than the traditional radar based on velocity measurement in time domain. This new radar efficiently increses the measurement range and has the ability of multiple-target detection and spin measurement that the traditional radar does not have. This paper describes the principle and realisation of the velocity maesurement in frequency domain, presents the organization and functions of a ballistic analyser based on this principle and shows some experimental results which demonstrate the advantages of the new radar system.
