Some aspects of usage of the pseudo noise sequences in the radiolocation systems

Pseudo noise sequences (Barker's codes, M sequences etc.) widely use in communication and navigation systems. But for nowadays this kind of signals almost has no application in the radiolocation systems. This work investigates aspects of usage of pseudo noise sequences (PNS) in the radiolocation systems, some aspects of generating and processing of the input processes. Main emphasis was made on signal-to-noise ratio behaviour in the systems with pseudonoise signals in comparison with classic radiolocators.
