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] like figure 1 As show...

Abstract

The invention belongs to the technical field of navigation information processing. The invention relates to a performance evaluation method of a composite navigation fusion algorithm. The method comprises steps: firstly, constructing a composite navigation system performance multi-level index system; determining a composite algorithm performance sub-target weight distribution set of the compositenavigation system and a weight distribution set of an evaluation index; constructing a membership matrix and then carrying out comprehensive evaluation. According to the method, an FAHP method and anFCE method based on logarithm least square are combined; the method solves the problems that the fusion algorithm of the ballistic missile-carried inertial / land-based / satellite composite navigation system has many performance influence factors and is difficult to quantitatively evaluate, can determine the weight vector of the fusion algorithm performance evaluation index, utilizes the fuzzy operator to carry out weighted synthesis, and has the advantages of quantifiable index weight, strong comprehensive evaluation capability and the like.

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...
