An original concept of building a multi-channel receiving modules of the C-band active phased array antenna (APAA) for on-board and ground-based communication systems and radar is presented. Construction of multipath receiving APAA is impossible without solving the problem of building multi-channel receiver modules. The number of beams in the system determines the number of phase shifters involved...
Theoretical and experimental research of nanostructured carbon materials with adjustable transparency of the tunnel barriers that control the threshold of their autoemission are presented. It is shown that increasing the transparency of the potential barrier at autoemission can be accomplished by increasing self-energy of the tunneling electron at size quantization. The role of surface states in nanodiamond...
In this paper typical approaches to mitigate single event effects using spatial redundancy were reviewed. The specificity of receivers input tracts were described. The low power techniques as the clock gating have a significant impact on the work conditions of a digital receiver. A novel modification was proposed for storage cells which are insensitive to radiation-induced single event upsets such...
