摘      要：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 *** 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 *** proposed method orthogonally demodulates the wideband and arbitrary RF signal to complex baseband by a known local oscillator（LO） ***,it takes measures to obtain the delay reconstruction signal of baseband signals based on the dynamic transmission delay between a ground station and a ***,it manages to obtain the delay reconstruction signal of LO *** simulation output signal（the delayed RF signal） can be achieved through the synthesis of the two delay reconstruction signals mentioned *** principle and its related key technology are described in detail,and the realizable system architecture is given.
