提高角误差通道信噪比跟踪技术的研究

Study on the Track Technique with Improving Signal-to-Noise Ratio of Angle Error Channel

在和差法单脉冲跟踪系统中，为了使差通道接收机获得高信噪比的角误差信号，本文提出在天馈系统中应用天线和混合环路新的组合，提高了角误差通道信噪比．它不仅具有单脉冲跟踪技术的特点，由于角误差通道信噪比获得提高，还具有跟踪距离远，角跟踪精度高，工作范围广。

This paper points out that, in the single pulse track system, in order to obtain angle error signal with high signal-to -noise radio for the difference channel receiver by using sum and difference methods. It has been improved signal-to-noise ratio of angle error channel by appling new combination of antenna and mixing loop in aerial feeder system. It not only is characteristic of single pulse, but also has advantage of far distance track, high accuracy angle track, wide working range and strong anti-disturbance, etc, owing to gaining a higher signal-to-noise radio of angle error channel.
