Analysis of the application of pseudorandom sequences in weapon systems

Pseudorandom sequences play a key role in modern information-communication and computational systems. Research directions devoted to the generation and processing of pseudorandom sequences are an integral component of the development of weaponry and military equipment, since in this domain pseudorandom sequences are employed to provide secure communication channels, covert information transfer, formation of interference-resistant signals, as well as in radar and navigation systems. The use of such sequences makes it possible to increase accuracy and robustness against the effects of electronic warfare means. This problem of generating high-quality pseudorandom sequences acquires particular importance in the conditions of contemporary armed conflict. The information advantage and the resilience of communication systems to interception or jamming determine the effectiveness of troop command and the employment of certain high-technology weapon systems. Application of pseudorandom sequences in spread-spectrum technologies provides not only enhanced interference resistance of radio channels, but also complicates detection and decryption of signals by the adversary. This is directly relevant for unmanned aerial systems, navigation systems, and precision strike means. Moreover, pseudorandom sequences form the basis of cryptographic algorithms that protect operational information, command-and-control data, and telemetry of weapon systems. Pseudorandom sequence generators are used in automated command-and-control systems, information networks, and specialized military software solutions. Thus, in view of trends toward digitization and increased autonomy of weapon systems, and given the stringent requirements for throughput, statistical quality, and cryptographic strength of pseudorandom sequences, investigation of the operating environment and generation methods for pseudorandom sequences is an urgent task directly related to improving the performance of current and prospective weapon systems, as well as to ensuring information and cyber security in the military domain.
