Embodiment Construction

[0036] The present invention will be further described below by means of the accompanying drawings and specific embodiments.

[0037] The execution steps of the evaluation method proposed by the present invention can be summarized as follows:

[0038] Step 1. Construct a multi-level structure system

[0039]According to the factors and correlations contained in the composite algorithm performance of the composite navigation system, the key judging criteria are decomposed, and the domain set of judging sub-goals, indicators and evaluation levels is constructed to form a multi-level index system structure. Let the evaluation sub-goal and evaluation level discourse set be U and V respectively:

[0040] U={u 1 ,u 2 ,u 3},V={V 1 ,V 2 ,...,V 5} (1)

[0041] where u i is the i-th sub-objective in the first layer (the highest layer), which is determined by the p indicators in the second layer, that is, u i ={u i1 ,u i2 ,...,u ip}, i=1,2,3.

[0042] Such as figure 1 As s...

Abstract

The invention belongs to the technical field of navigation information processing, and specifically relates to a performance evaluation method of a composite navigation fusion algorithm. Firstly, a composite navigation system performance multi-level index system is constructed, and the composite navigation system composite algorithm performance sub-target weight distribution set and the weight of the evaluation index are determined. Assignment set, construction of membership degree matrix and comprehensive evaluation. This method combines the FAHP method based on logarithmic least squares and the FCE method, and solves the factors affecting the performance of the fusion algorithm of the inertial / ground-based / satellite composite navigation system equipped with ballistic missiles. For many problems that are difficult to evaluate quantitatively, the weight vector of the performance evaluation index of the fusion algorithm can be determined, and the fuzzy operator can be used for weighted synthesis, which has the advantages of quantifiable index weight and strong comprehensive evaluation ability.

Description

technical field [0001] The invention belongs to the technical field of navigation information processing, and in particular relates to a method for evaluating the performance of a composite navigation fusion algorithm based on logarithmic least squares FAHP-FCE. Background technique [0002] Inertial / ground-based / satellite composite navigation is one of the commonly used navigation methods for ballistic missiles. Under all-weather, all-weather, complex electromagnetic interference conditions, the accuracy and reliability of the ballistic missile's composite navigation system depends on the performance of its fusion algorithm. Before the fusion algorithm is put into application, the performance evaluation of the algorithm provides a basis for designing and determining the system parameters that meet the performance requirements of the composite navigation system, and optimizing the system parameters. At the same time, it provides an algorithm verification platform for the na...
