摘要
在阵列式射频仿真系统中,采用射频天线阵列模拟目标信号角度运动,其控制原理是基于辐射信号的幅相合成。当工作频率发生捷变时,由于阵列控制器件的频响等因素,目标阵列角位置的模拟精度将发生变化。本文从目标阵列的角位置模拟原理出发,以二元组为例分析了频率捷变对射频仿真目标阵列精确位置控制系统的影响,为研究捷变频状态下目标阵列的精位控制技术提供了依据。
Simulating the angle movement of the signal of the target by means of RF antenna aeria array in the array radio frequency simulation system （RFSS）, the control principle of the simulation of the azimuth moving target signal is based on the integration of amplitude and phase of the radia- tion signal. The frequency agility will cause error to the accuracy of azimuth simulation because of the frequency response, etc of aerial array controlling module. Based on the principle of the azimuth simulation of target signal, two-element antenna is taken as an example, an analysis of the influence to precision azimuth control of target aerial array caused by frequency agility is discussed in this paper, which will provide basis to the research of the precision control technique of aerial array under the carrier frequency agility.
