摘　　要：微波干涉测量方法将火炮炮管作为圆波导进行能量传输,是研究火炮膛内弹丸运动参数的有效手段。微波干涉仪天线工作频率的选择不仅影响能否获取膛内运动参数,也决定获取信号的信噪比,影响到初始弹道分辨率及测试精度。文章对此进行了分析。Microwave interferometric method, which uses gun tube as circular waveguide for energy transmission, is an effective means to study the motion parameters of projectiles in gun chamber. The selection of working frequency of microwave interferometer antenna not only affects whether the in-bore motion parameters can be obtained, but also determines the signal-to-noise ratio of the signal, which affects the initial trajectory resolution and test accuracy. This paper analyzes this.
