VELOCITY ERROR ANALYSIS OF COHERENT AND NON-COHERENT TRANSPONDING TRACTORY MEASUREMENT SYSTEMChengfang, Huang 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper introduces two transponders combining coherent transponding and non-coherent
transponding for multistatic trajectory measurement system and carrier Doppler frequency
extraction principle, then derives each model of the velocity error for noise. The expressions
of velocity error resulted by noise in coherent, IF-modulated and IF transform transponding
configurations are also described. The conclusion is drawn: the system velocity error for noise
is related to the transponder transponding configuration. And, the velocity error in coherent,
IF-modulated and IF transform transponding configurations are compared in this paper.
