Ultra Wideband Technology for Micro Air Vehicles Data Links Systems
In This paper,an Ultra-wideband (UWB) data link for the Micro Air Vehicles (MAVs) is proposed which can be used for the low probability of intercept and detection (LPI/D)transmission of digital voice,data and high resolution video image. The achievable range-data rate performance of the reliable UWB data link for long ranges is evaluated and compared,considering direct sequence spread spectrum (DSSS)modulationInthe low-data single carrier-based impulse radio system. Taking into account the Doppler effect on the wideband DSSS signal,a scale-lag Rake receiver capable of leveraging the diversity that results from mobility is studied. Novel results of this research work indicate that a reliable UWB data link for MAVs can be established by compromising between range and performance of transmission.
