Embodiment approach

[0038] Step 1. At least two sensors with different working principles detect and obtain multi-attribute target measurement data;

[0039] The F1 aircraft and the F2 aircraft fly in formation to detect the T1 target and the T2 target respectively.

[0040] The F1 machine detects parameters such as the distance d11, azimuth r11, speed v11, and distance change rate a11 of the T1 target relative to the own machine, and the F1 machine detects parameters such as the distance d12, bearing r12, speed v12, and distance change rate a12 of the T2 target relative to the machine. The F2 machine detects parameters such as the distance d21, azimuth r21, speed v21, and spectrum p21 of the T1 target relative to the own machine, and the F2 machine detects parameters such as the distance d22, azimuth r22, speed v22, and spectrum p22 of the T2 target relative to the own machine.

[0041] For example:

[0042] F1T1={80.7, 5°2′, 305, 1.2};

[0043] F1T2={62.5, 11°9′, 270, 1.8};

[0044] F2T1={80...

Abstract

The invention belongs to the technical field of data processing, and particularly relates to a multiple-attribute target data association method and device. The method comprises the following steps: S1, acquiring multi-attribute target measurement data detected by at least two sensors with different working principles; S2, mapping the measurement data into a fuzzy set on a multi-attribute discourse domain; S3, establishing a membership relationship between every two targets based on multiple attributes through a preset membership function; S4, establishing a target data incidence matrix according to the membership relationship; and S5, resolving an optimal target matching association scheme, and determining a target association relationship. The problem that multi-sensor measurement target data cannot correspond to one another is solved, the correct incidence relation of multi-attribute target data is achieved, the method is suitable for engineering practice, and the method is effective and feasible.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a multi-attribute-based target data association method and device. Background technique [0002] Target data generally contains a variety of attributes. Establishing the relationship between target data of different detection equipment is the premise and basis of information fusion and target tracking, which directly affects the accuracy and rationality of subsequent information processing. In the complex air situation environment, there are errors in the multi-attribute measurement of target data by airborne detection equipment, and the target data measured by special-shaped sensors are irrelevant, so the detection efficiency of "1+1>2" cannot be exerted. In order to give full play to the advantages of multi-sensor measurement and solve the problem of fuzzy correspondence between multi-sensor measurement target data, it is necessary to establish ...
