摘要
论述了Ka频段圆波导TE11和TE21模自跟踪体制和S频段正十字排列四喇叭自跟踪体制共用两信道自跟踪接收机问题.导出了来波及地面天线S频段和、差信道极化特性引起的角误差电压的交叉耦合系数公式.还可以进一步使S/Ka两个频段共用一套能跟踪(直接序列)扩频信号源的伪单脉冲(单信道单脉冲)自跟踪接收机.
A dual-channel tracking receiver is commonly used for the circular waveguide TE11 and TE21 modes auto tracking system in Ka-Band and four-horn monopulse autotracking system in S-Band by switchover. The cross coupling of the angle error voltage due to polarization performance of the coming wave and antenna＇s sum and difference channel radiation field and non-ideal 3dB 90° bridge are developed. Then, a pseudo monopulse tracking receiver is used in S/Ka dual frequency bands by switchover, with the pseudo monopulse tracking receiver facilitating tracking for a direct sequence spread spectrum signal source.
