Embodiment Construction

[0065] The present invention will be further described below in conjunction with accompanying drawing:

[0066] It is assumed that the aircraft carries 4 jamming devices (M=4, respectively numbered "1" to "4"). The jamming patterns of each jamming device are random noise FM jamming, smart noise convolution jamming, and false target deception jamming. They are numbered "1", "2" and "3", and interfere with 8 networked radars (N=8, respectively numbered "1" to "8"). as attached image 3 Shown is the interference object corresponding to the optimal interference strategy finally obtained by the present invention; Figure 4 is the interference pattern corresponding to the optimal interference strategy finally obtained in the present invention.

[0067] as attached figure 1 As shown, it is a diagram of each processing link of the radar information involved in the present invention; figure 2 For the scheme design drawing of the present invention; Specifically comprise the followi...

Abstract

The invention belongs to the technical field of electronic interference, and relates to a multi-interference effectiveness value-based swarm intelligence interference decision making method. Accordingto the method, an aircraft acquires detection target information from an electromagnetic environment, and an objective function is constructed with the adaptive weighted sum of the detection probability and positioning accuracy of a networked radar; the objective function is optimized by a swarm intelligence technology; a continuous solution is discretized, and a genetic algorithm crossing thought is introduced; and a finally-generated interference strategy is sent to an aircraft interference device. An interference effect is evaluated with a plurality of indicators; the two detection indexes, namely, the detection probability and positioning accuracy of the networked radar, are combined into the interference decision objective function, and therefore, the reliability of a calculated objective function value is effectively improved, and the correctness of an interference decision is improved; the adaptive weighted sum method and the swarm intelligence algorithm are combined, and therefore, the convergence speed of the algorithm is improved, the adaptability of optimization is improved, computational complexity is reduced, and the global search capacity of the algorithm is enhanced.

Description

technical field [0001] The invention belongs to the technical field of electronic interference, and in particular relates to a group intelligent interference decision-making method based on multiple interference effectiveness values. Background technique [0002] Jamming decision-making is an extremely important link in electronic jamming, and its accuracy and real-time performance directly affect the jamming effect on detection targets. Radar jamming decision-making is based on information such as the number, location, and parameters of detection targets obtained by the reconnaissance system, combined with our existing jamming resources and tactical needs, effectively assessing the environmental situation, and quickly and reasonably allocating resources to achieve full use of jamming resources. process. The traditional independent interference method can no longer fully meet the interference needs. To develop a reliable and effective evaluation method has become the bottle...
