Abstract
Applying Impulse Radio-Ultra Wideband ( IR-UWB ) signal in space tracking, telemetry and command( TT&C) system can effectively improve concealment,anti-interference performance and measure-ment performance of TT&C system. This paper intends to combine Direct Spread-Pulse Amplitude Modula-tion(DS-PAM),time hopping-pulse position modulation(TH-PPM) signal and pulse shape modulation ( PSM) technique to constitute a new combination of pulse modulated ultra-wideband signal called DS-PAM-TH-PPM-PSM-UWB ( Direct Spread-Pulse Amplitude Modulation-Time Hopping-Pulse Position Modulation- Pulse Shape Modulation-Ultra Wideband ) signal . By using the lognormal shadowing path loss model,the transmission performance is analyzed. Its anti-interference performance is analyzed under single-frequency signal interference condition and its measurement performance is analyzed using ambigui-ty function. Simulation results show that the transmission performance,anti-jamming performance and per-formance measurement of the combined signal are improved compared with conventional DS-PAM-UWB signal and TH-PPM-UWB signal. Therefore more choices are provided for application of IR-UWB signal in TT&C field.关键词
