Abstract
A generalized simulation method of the tracking, telemetry and control (TT&C) channel, which is applicable to wideband and arbitrary radio frequency (RF) signal, is proposed. It can accurately simulate the dynamic transmission delay of the arbitrary RF signal in channels, especially regardless of any prior knowledge including signal form, signal parameters, and so on. The proposed method orthogonally demodulates the wideband and arbitrary RF signal to complex baseband by a known local oscillator (LO) signal. Whereafter, it takes measures to obtain the delay reconstruction signal of baseband signals based on the dynamic transmission delay between a ground station and a responder. Meanwhile, it manages to obtain the delay reconstruction signal of LO signals. The simulation output signal (the delayed RF signal) can be achieved through the synthesis of the two delay reconstruction signals mentioned above. The principle and its related key technology are described in detail, and the realizable system architecture is given.
