Together with the development of technology, Unmanned Air Vehicle System (UAVS)'s usage is growing day by day. Accordingly, producing and using UAVS is a big competition among the countries. So it is very important that UAV's have to be firm and reliable. Another important point is the data links; data transmission must be accurate and continuous. Nowadays UAVS are produced by many companies. But information security problem still continues. Therefore the growth of the UAV number and the need for reliable data transfer have caused question marks about frequency management, the way of data transmission. For this reason lots of research and development efforts are being handled. This document has been briefly mentioned the UAV systems and communication subsystems. 

“…Traditionally, spread spectrum is the most widely used technique for LPI. However, when data transmissions are evolving toward wideband, spread spectrum alone may not be enough because of the reduced space of spreading gain [7].…”

The use of signal processing techniques to protect wireless transmissions is proposed as a way to secure wireless networks at the physical layer. This approach addresses a unique weakness of wireless networks whereby network traffic traverses a public wireless medium making traditional boundary controls ineffective. Specifically, a randomized array transmission scheme is developed to guarantee wireless transmissions with inherent low-probabilityof-interception (LPI). In contrast to conventional spread spectrum or data encryption techniques, this new method exploits the redundancy of transmit antenna arrays for deliberate signal randomization which, when combined with channel diversity, effectively randomizes the eavesdropper’s signals but not the authorized receiver’s signals. The LPI of this transmission scheme is analyzed via proving the indeterminacy of the eavesdropper’s blind deconvolution. Extensive simulations and some preliminary experiments are conducted to demonstrate its effectiveness. The proposed method is useful for securing wireless transmissions, or for supporting upper-layer key management protocols.
