Embodiment Construction

[0032] figure 1 A sensor target allocation method for a multi-objective optimization differential evolution algorithm provided by an embodiment of the present invention, which includes the following steps:

[0033] S1. Obtain characteristic parameters of the monitored target, evaluate the characteristic parameters to obtain the target importance of the target, and perform normalization processing on the target importance to obtain the target threat weight.

[0034] For example, m targets are obtained from the information to be monitored, feature parameters are extracted, and the target importance is estimated to be w i (i=1,2,...,m), and the estimation of the importance of the specific target can be calculated by common methods such as multi-attribute decision-making, fuzzy logic method, Bayesian network or neural network. Calculate the normalized threat weight for the obtained target importance.

[0035] In the step S1, the calculation formula of the target importance is as...

Abstract

The invention discloses a sensor target allocation method based on a multi-objective optimization differential evolution algorithm. The method includes: calculating the importance of the target according to the target information, establishing a sensor target allocation constraint multi-objective optimization function, coding an allocation scheme and generating initial population chromosomes, Use the differential evolution algorithm to generate the offspring plan population, merge and screen the population, obtain the Pareto front-end solution set of the distribution plan, etc. The present invention provides a Pareto set multi-objective optimal allocation strategy in combination with the characteristics of differential evolution algorithm in group difference heuristic random search, which is simple and easy to use, good in robustness, and has strong global search ability; Based on the performance function, the sensor utilization function is added to transform the allocation problem into a multi-objective optimization problem, which can save sensor resources as much as possible while meeting the monitoring accuracy requirements, and realize the reasonable and effective allocation of sensor resources.

Description

technical field [0001] The invention relates to the technical field of information fusion, in particular to a sensor target allocation method and system of a multi-objective optimization differential evolution algorithm. Background technique [0002] With the development of science and technology, a large number of multi-sensor systems facing complex application backgrounds have emerged, and have been widely used in various fields such as industry, agriculture, transportation, weather forecasting, environmental monitoring, and earth science observation. In order to give full play to the collaborative detection performance of multi-sensor systems, the sensor resources must be allocated scientifically and rationally, so the concept of sensor management in the field of information fusion has emerged. Sensor management refers to the use of multiple sensors to collect information about the target and the environment, task-oriented, and under certain constraints, reasonably alloca...
