Flight path continuity assessment method and system under complex conditions

Abstract

The invention discloses a flight path continuity assessment method and system under complex conditions, and the method comprises the steps: obtaining truth-value flight paths and integrated flight paths, and respectively forming truth-value flight path sequence and an integrated flight path sequence; Carrying out the optimal pairing of the truth-value flight paths and integrated flight path points according to the similarity of the integrated flight path points and the truth-value flight paths; building the corresponding relation between each integrated flight path point and the corresponding truth-value flight path based on an optimal pairing principle, and carrying out the statistics of continuous time differences of different integration batch numbers in the relation corresponding to one truth-value flight path in an evaluated time period, and calculating the continuous rate of the single flight path; and calculating the integrated continuous rate through the continuous rate of each single flight path. The method is different from a conventional method for to-be-evaluated flight path selection and continuity assessment, is suitable for conditions of dense targets, radar interference or poor natural conditions, and irons out the defect that the flight path continuity assessment cannot be carried out accurately in a complex environment.

Description

technical field [0001] The invention relates to the technical field of data fusion performance evaluation, in particular to a method and system for evaluating track continuity under complex conditions. Background technique [0002] The data fusion performance evaluation technique is C 4 The important subject of ISR system research, analysis, development and evaluation has always been a difficult problem in the process of system development. [0003] The track continuity index is one of the key indicators in the performance evaluation of data fusion. Maintaining track continuity is the basis for maintaining the clarity and stability of the situation, and is an important basis for the commander's combat decision-making. Track continuity mainly reflects the stability of the system for track fusion. Intuitively speaking, it refers to the degree of consistency of track batch numbers. The longer the same batch number is maintained, the better the track continuity is; otherwise, t...

Problems solved by technology

However, the fusion system collects and processes a wide variety of information, the application scenarios are very different, and the natural environment and electromagnetic environment are complex and changeable, resulting in the associated batch number comparison table is often incorrect, making it more difficult to evaluate track continuity objectively and fairly. difficulty

In addition, the traditional evaluation method is inaccurate to evaluate the continuity of the track by the number of track splits, ignoring the proportion of each split track to the whole track
