Multi-base radar radio frequency stealth optimization method based on Stackelberg game

Abstract

The invention discloses a multi-base radar radio frequency stealth optimization method based on Stackelberg game. The method comprises the following steps of: S1: obtaining path propagation loss between each radar and a target and path propagation loss between each radar and an enemy interception receiver in a multi-base radar system; S2: establishing a multi-base radar power distribution model based on a non-cooperative game according to a preset target detection tracking signal-to-interference-and-noise ratio threshold and each radar transmitting power upper limit; S3: calculating game benefits obtained by the enemy interception receiver from the multi-base radar; S4: acquiring the iterative expression of transmitting power of each radar in the multi-base radar system; and S5: increasingthe unit receiving power price of the interception receiver, and continuously updating in an iteration mode until the utility function of the interception receiver is converged. The multi-base radarradio frequency stealth optimization method meets the given target detection tracking performances, effectively controls the transmitting power of each radar in the multi-base radar system, and improves the radio frequency stealth performance of the multi-base radar.

Description

technical field [0001] The invention relates to radar signal processing, in particular to a multi-base radar radio frequency stealth optimization method based on the Stakelberg game. Background technique [0002] In modern high-tech warfare, radar has become an indispensable equipment and means to obtain battlefield information. In radar electronic warfare, the radar and the intercept receiver are the opposite sides of the "contradiction". With the rapid development of the enemy's interception receiver and anti-radiation missile technology, radar, as a "contradictory" party, is increasingly threatened by its own survival in the increasingly complex electronic warfare electromagnetic environment. Radio frequency stealth technology is an effective way to improve the survivability of radar battlefields by adopting methods such as radiation energy management, frequency agility, and complex modulation.

Problems solved by technology

[0003] At present, there are methods that propose the idea of ​​multistatic radar radiation control based on game theory, which reduces the radio frequency radiation of multistatic radar systems to a certain extent, but this method does not take the enemy's interception receiver into the game model, and does not consider Intercept the game income of the receiver side, so the existing methods have a limited degree of reduction in the radio frequency radiation of the multistatic radar system
