Embodiment 1

[0067] Plan the 8 missions in the table below into a networked radar with 2 multifunction radars.

[0068]

[0069] Obviously, the task period in the table There is no integer multiple relationship between them. First, we need to determine the slot width and total period of each radar time axis, from Algorithm 1:

[0070] T 1 1 = 1 s t - s m a l l e s t p ~ n = 50 ( m s ) , T 1 2 = 2 n d - s m a l l e s ...

Embodiment 2

[0086] Simulation conditions: the multi-function networked radar includes 3 multi-function radars, the total number of independent variable tasks gradually increases from 3 to 80, the lower bound of the task dwell time is a random number between 5 and 25, and the upper bound is between 50 and 70 The default period of the task is a random number between 80 and 1000. Select four groups of different parameters α and β to compare and study the influence of parameters α and β on task planning.

[0087] Figure 4 is the fraction of tasks that are dropped during initialization. From Figure 4 It can be seen that the smaller the interval length between parameters α and β, the more tasks are discarded during initialization. Among them, α=β=1 means that the period of the task is a fixed value, which is equivalent to planning the task directly without adjusting the period of the task. At this time, the proportion of discarded tasks is close to 100%, and almost no tasks are planned succ...

Abstract

The invention discloses a multifunctional radar network mission planning method. The method comprises the steps of firstly establishing a radar mission model, wherein a default period of each radar mission in the model is an irregular any positive real number, and a radar network comprises a plurality of multifunctional radars; secondly setting different slot widths and a total period for each radar time axis according to parameters of existing missions, allocating each radar mission to the radar time axis with a minimum deviation between the slot width and the period of the radar mission, and updating the period of each mission; and finally planning each mission in the corresponding radar by utilizing a heuristic algorithm. According to the method, a plurality of the arbitrarily periodical radar missions can be planned on each radar in the multifunctional radar network.

Description

technical field [0001] The invention belongs to the technical field of multifunctional networking radar, and in particular relates to the design of a task planning method for multifunctional networking radar. Background technique [0002] 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 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, increases the radar target reflection area, and reduces the anti-interference ability and combat effectiv...
