Embodiment 1

[0031] Such as figure 1 As shown, the present embodiment provides a method for airborne self-defense deceptive jamming based on multivariate synthesis technology, including the following steps:

[0032] S1: When the enemy's monopulse radar emits a detection signal, the airborne jamming system of one's own side receives the detection signal and analyzes the detection signal to obtain the radar information of the enemy seeker. The acquired radar information of the enemy seeker includes the frequency of the detection signal, Power and incident angle, etc.;

[0033] S2: The own airborne electronic combat system synthesizes pre-programmed information by combining the enemy seeker radar information and false target position information, and uses the pre-programmed information to generate a multi-antenna feeding scheme. The pre-programmed information includes the antennas in the own airborne multi-antenna system The selection of , and the power and phase information of each antenna ...

Abstract

The invention discloses an onboard self-defense deception type interference method based on a multi-synthesis technology, and relates to the technical field of electronic warfare radar countermeasure.The method comprises the following steps that: S1: when an enemy single-pulse radar emits a detection signal, an own side onboard interference system receives the detection signal to obtain enemy seeker radar information; S2: an own side onboard electronic warfare system analyzes the enemy seeker radar information, and the enemy seeker radar information is combined with false target information to be synthesized into pre-programming information, and the pre-programming information is used for generating a multi-antenna feeding scheme; and S3: an own side onboard multi-antenna system calls a multi-antenna feeding scheme to emit an interference signal to synthesize a false target, and therefore, the enemy single-pulse radar can not discriminate the true target of the own side. By use of themethod, field distortion formed during multi-antenna radiation field synthesis is used for interfering the judgment of the radar for a field normal line, so that a wider interference range, a higherdegree of freedom and a bigger interference angle are generated, and an interference effect with better fraudulence is obtained.

Description

technical field [0001] The invention relates to the technical field of electronic warfare radar countermeasures, and more specifically relates to an airborne self-defense deceptive jamming method based on multiple synthesis technology. Background technique [0002] In modern high-tech warfare, electronic warfare has become an indispensable and important part, and the research on electronic warfare technology is directly related to the development of radar technology. As the trump card and power multiplier in information warfare, electronic jamming is an important means to block the enemy's command system and defeat the enemy's early warning system. Especially for the air battlefield, the existence of air-guided radar weapons is a major threat to the survival of fighter jets. Among many radar tracking and guidance technologies, monopulse radar is widely used in the military field, especially in the field of precision guidance. Because monopulse radar has strong anti-interfer...
