摘要
单脉冲单通道跟踪系统具有设备简单、实时性好、动态滞后小的特点,但由于跟踪通道噪声增加,致使跟踪精度较低。在实际应用中,单通道信号合成的方法不同,对跟踪精度的影响也不同。给出了场放前合成的实现方案,在分析其单通道信号形成、角误差解调原理的基础上,推导出该方案下的跟踪精度分析公式,说明了单通道跟踪系统的跟踪精度与单通道合成耦合度的关系。
The single-channel monopulse tracking system features simple equipment composition, good real-time performance and small dynamic lag, but tracking channel noise can result in low tracking accuracy. In practice, the different signal combination methods have different effect on the tracking accuracy. In this paper, an implementation scheme of combination before the FET amplifier is provided. On the basis of analyzing the single-channel signal formation and the angle error demodulation principle of this scheme, a tracking accuracy analysis formula is derived.The results show that the tracking accuracy of a single-channel monopulse tracking system is raleted to coupling degree of single- channel combination
