摘　　要：提出了光纤延迟线在相控阵阵列天线中总的噪声系数的计算方法,推导了噪声系数的计算公式,并对各个光电参数对噪声系数的影响进行了分析。结果表明,减小光纤链路损耗、增加阵元数、增大放大器增益等,可以减小光纤延迟线阵列的噪声系数。The calculation method for total noise figure of fiber delay line in phased array antenna is presented.A general formulation for calculating of the total noise figure of array antenna is deduced.Influence of each factor on the noise coefficient is analyzed.The results show that,increasing the gain of the amplifier and the number of element,decreasing the optical link loss and so on,can reduce the total noise figure.
