在解调型应答机中
解调的基带信号和伴随的噪声一起再调制和转发。本文针对线性通道中相干解调、有预限幅的相干解调和鉴频解调三种情况
分析了转发噪声与系统参数的关系。理论分析已为实验所证实。本文结果可用于无线电测轨或数据传输系统的设计。
In demodulation type transponder the demodulated baseband signal accompanied by noise is used for further modulation and retransmission. The relationships between the retransmitted noise and system parameters are analysed for three cases
i.e. coherent demodulation in linear channel
coherent demodulation with pre-limiter and frequency discrimination demodulation. The theoretical analysis has been confirmed by experiments. Results of
this article can be used for radio system design of orbit determination and data transmission.
