Problems solved by technology

However, distributed MIMO radar, as a radar network system, has many controllable parameters. Optimizing a single parameter does not significantly change the stealth performance of the radar, and will also cause unnecessary waste of other resources.

Abstract

The invention discloses a distributed MIMO radar resource combined optimization method based on radio frequency stealth, and belongs to the technical field of distributed MIMO. According to the method, the upper and lower bounds of transmitting power and residence time of each set of radar are determined according to the battlefield environment and the performance of the radar; then a distributed MIMO radar residence time and power resource combined optimization model based on radio frequency stealth is constructed with minimizing of the interception probability of the system acting as the target under the condition of meeting the target tracking performance, and the model is solved through a nonlinear programming genetic algorithm; and the optimal solution of the residence time and the transmitting power of each set of radar is obtained through numerical calculation so that the minimum interception probability of the distributed MIMO radar system meeting the constraint conditions can be obtained. The interception probability of the distributed MIMO radar system can be reduced and the radio frequency stealth performance of the system can be enhanced.

Description

technical field [0001] The invention relates to a radio frequency stealth-based distributed MIMO radar resource joint optimization method, belonging to the technical field of distributed MIMO radar. Background technique [0002] With the increasingly fierce electronic countermeasures in the modern battlefield, the living environment of radar has been seriously threatened. Radio frequency stealth technology can significantly reduce the probability of radar being detected, discovered, identified and attacked, and is an important guarantee for improving the battlefield survivability and combat effectiveness of radar and its carrier platform. Compared with radar stealth and infrared stealth, radio frequency stealth technology is different. It does not reduce target characteristics without limit, but effectively controls target characteristics on the basis of meeting equipment function and performance requirements, and improves its low interception performance. [0003] Based on...
