Distributed airborne electronic countermeasure system architecture

Abstract

The invention belongs to the field of airborne electronic countermeasure system architecture design, and particularly relates to a distributed airborne electronic countermeasure system architecture. The system architecture comprises an electronic warfare type nose, a baseline type electronic warfare system, a medium-frequency band electronic warfare aperture and a radar type nose, the baseline type electronic warfare system is arranged at the front edge and the rear edge of a wing, the medium-frequency band electronic warfare aperture is arranged to be in omnidirectional coverage, and the radar type nose is arranged on the base line type electronic warfare system. The electronic warfare type machine head, the baseline type electronic warfare system, the medium-frequency band electronic warfare aperture and the radar type machine head are all connected with the signal processing platform, and the signal processing platform is used for managing and scheduling the electronic countermeasure function of each subsystem. The transmission type electronic warfare capability in a strong electromagnetic environment can be realized through the electronic warfare type nose, the electronic warfare capability of covering an omnidirectional 4 pi space is realized, meanwhile, a multifunctional integrated design is adopted, the volume, weight and power consumption of a radio frequency sensor of the unmanned aerial vehicle are reduced, and the problem of position contradictions of multi-antenna aperture layout is solved.

Description

technical field [0001] The present application belongs to the field of airborne electronic countermeasures system architecture design, and in particular relates to a distributed airborne electronic countermeasures system architecture. Background technique [0002] The fighter electronic countermeasure system mainly completes the functions of electromagnetic situational awareness and electronic self-defense jamming, and is an important avionics system to ensure the survivability of the fighter. The electronic countermeasure function on traditional fighters is mainly realized by the leading edge and trailing edge of the wing, which is slightly insufficient in the current strong electromagnetic combat environment, which is mainly reflected in the following shortcomings: The ring-shaped area has functions such as electromagnetic situational awareness and electronic self-defense interference, and cannot cover the upper back and upper belly of the aircraft, where there are dead sp...

AI Technical Summary

Problems solved by technology

The electronic countermeasure function on the traditional fighter is mainly realized by the leading edge and the trailing edge of the wing, which is slightly insufficient in the current strong electromagnetic combat environment. This is mainly reflected in the following shortcomings: a. Existing fighters are only used around The circular area has functions such as electromagnetic situation awareness and electronic self-defense interference, but it cannot cover the upper part of the back and belly of the aircraft, and there are dead spots in capabilities; b. The existing fighter electronic countermeasure system is mainly designed for fighter survivability, and does not have strong Penetrating electronic warfare capabilities cannot provide cover for formations; c. The existing electronic warfare functions are separated from radar detection and inter-machine communication functions, and the degree of sensor integration is low. The cost is high, which affects the performance of the aircraft platform
