Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the implementation methods and accompanying drawings.

[0039] Step 1: Modeling the radar mission planning problem.

[0040] The radar task is modeled as the transmission, waiting and receiving process of the radar pulse, and the residence time of the radar task is the sum of the transmission, waiting and receiving time of the radar pulse, and the present invention represents the residence time of the nth radar task as d n ,Such as figure 1 shown.

[0041] Consider planning N radar tasks into a radar network with M homogeneous radar units, each radar unit corresponds to a time axis length L, and radar tasks can be assigned to different radar units for parallel execution, but the same The radar tasks on the radar time axis cannot overlap, and once the same radar task starts, it must be exec...

Abstract

The invention discloses a multifunctional networked radar task planning method based on a branch-and-bound method. The multifunctional networked radar task planning method adopts the branch-and-boundmethod of a tree structure to realize the traversing of a feasible solution of a problem, and introduces a pruning operation so as to reduce the computation amount significantly. The multifunctional networked radar task planning method can plan radar tasks with different parameters and priorities into radar units of a radar network, and ensures load balance of the radar units. Although an existingheuristic radar task planning method can complete the radar task planning, the existing heuristic radar task planning method can only acquire a suboptimal solution, and the computation cost is hard to estimate. Compared with the existing heuristic method, the total cost of a radar task planning scheme obtained by adopting the multifunctional networked radar task planning method is lower.

Description

technical field [0001] The invention relates to multifunctional networking radar technology, in particular to the radar mission planning technology of multifunctional networking radar. Background technique [0002] The so-called radar task planning is to assign a given radar task to one or more specific radars to execute. [0003] With the development of modern science and technology, the threats faced by combat platforms are increasing day by day, and the electromagnetic environment in which they work is also becoming more and more complex. Combat platforms have to be equipped with more and more electronic equipment. In particular, mobile platforms, such as aircraft and ships, must be equipped with multiple radars at the same time to deal with different radar tasks such as reconnaissance, interference, and detection. The increase of electronic equipment not only consumes a lot of energy and occupies more space, but also weakens the maneuverability of combat platforms, incr...
