Abstract:

With the continuous development of modern electronic confrontation technology and military equipment, the detection ability of passive detection system to aircraft and its active electronic equipment has been significantly improved. The survivability and penetration ability of aircraft in modern combat environment are seriously threatened. Aircraft radio frequency(RF) stealth technology is an important technical way to improve aircraft battlefield survivability by controlling the RF radiation of airborne radar, data link, altimeter, electronic confrontation and other active electronic equipment, and plays an important role in today's battlefield. In this paper, the research of aircraft RF stealth technology is overviewed. Firstly, the basic concept and research status of RF stealth technology are described, and the basic principle and realization way of RF stealth technology are introduced. Then, the research achievements in the field of RF stealth technology are reviewed from the aspects of RF stealth performance evaluation system, minimum radiation power control, low sidelobe digital beamforming of design RF stealth signal waveform, multi-sensor cooperation and management, etc. Finally, based on the summary and analysis of the existing research achievements, aiming at the problems existing in the development of RF stealth technology, the future development trend of aircraft RF stealth technology is prospected.

Key words: radio frequency (RF) stealth, radiation power control, digital beamforming, design of RF stealth signal waveform, low probability of intercept (LPI), multi-sensor cooperation and management
