Currently, there is a contradiction between the need to increase the throughput and reduce the reaction time to new threats of aviation electronic warfare systems and the existing limitations of weight and size characteristics, energy consumption and material costs.

The task of ensuring the protection of aviation from guided weapons is becoming more and more urgent, and the question of what means of electronic warfare it should be equipped with is open. As a result of equipping advanced radar stations with technical solutions that allow emitting probing signals with rapid frequency tuning from pulse to pulse in the band of several gigahertz, a requirement is imposed on promising electronic warfare equipment to detect enemy signals in a timely manner and emit interference, thereby increasing the probability of an enemy miss and, consequently, increasing the survival rate of the aircraft. At the same time, every pulse of the enemy's radar should be detected and there should be a reaction to each pulse in the form of interference, since with rapid frequency tuning, skipping even one pulse can allow the enemy to detect the aircraft.

The carrying capacity of aviation electronic warfare systems significantly affects the probability of detecting an enemy signal and, consequently, the probability of the object's survival. To ensure a high probability of survival of the facility, the throughput of the aviation equipment complex should be maximized. However, it should be noted that an increase in the capacity of the aviation equipment complex, as a rule, leads to a significant, up to unacceptable, increase in weight and size characteristics, energy consumption and material costs.

Scientific and methodological substantiation of the methodology for increasing the throughput of radio-electronic complexes of aviation equipment in modern conditions is relevant.

To increase the throughput of radio-electronic complexes of aviation equipment, it is advisable to choose a combination of the use of ultra-wideband digital devices capable of converting radio signals into digital form without preliminary transformations, and the use of digital radio signal processing technologies that allow simultaneous transfer to the intermediate frequency band of several sections of the operating frequency range with a frequency band equal to the intermediate frequency band, due to phase "color" heterodynes.

The developed approach can be applied in the design of electronic protection of aircraft of the 5th generation, the main idea of the development of which is multifunctionality, low visibility, small size and the optimal combination of efficiency-cost and, as a result, ensuring the integration of electronic means of the board.
