Abstract

The invention discloses an interference resource allocation method based on interference vectors and an NSGA-II algorithm, and the method comprises the steps: generating an interference resource allocation vector set, calculating the interference vector of each interference resource allocation vector to obtain an interference vector set, updating the interference resource allocation vector set and the interference vector set through a crossover and mutation method in the NSGA-II algorithm, and obtaining the interference resource allocation vector set. Layering and sorting the interference resource allocation vector set by using a fast non-dominated sorting and congestion degree method in an NSGA-II algorithm, and selecting the first 10 interference resource allocation vectors from the interference resource allocation vector set as the current optimal solution; and after repeated iteration, selecting one interference resource allocation vector in the optimal solution as an optimal interference resource allocation scheme. The optimal interference resource allocation scheme obtained by the invention has the advantages of wider application scenarios and independence of indexes.

Description

technical field [0001] The invention belongs to the technical field of radar, and further relates to an interference resource allocation method based on interference vector and NSGA-II algorithm in the technical field of radar interference. The present invention can be used for reasonably allocating interference resources when the interferer is covering the penetration target. Background technique [0002] When the interferer is covering the penetration target, the interference resources need to be allocated, so that the interferer can obtain the maximum interference effect under the condition of limited interference resources. To allocate interference resources, it is necessary to first determine the evaluation index, establish an objective function according to the evaluation index, and then substitute the objective function into the solution algorithm to obtain the optimal interference resource allocation scheme. When determining evaluation indicators, indicators such as...
