Air-ground missile hitting precision evaluation method based on error spectrum

Abstract

The invention discloses an air-ground missile hit precision evaluation method based on an error spectrum, and the method comprises the following steps: S1, carrying out the preprocessing of the air-ground missile hit precision data, so as to expand the sample size, and enabling the data to be converted into a relative distance error; S2, determining a key measurement index which can be used for evaluating the hitting precision of the air-ground missile system; S3, constructing an air-ground missile hitting precision attribute matrix; s4, establishing an air-ground missile hitting precision attribute competition matrix according to the air-ground missile hitting precision attribute matrix; and S5, solving the feature vector of the air-ground missile hit precision attribute competition matrix, and giving an air-ground missile hit precision evaluation result corresponding to the element value according to the element value in the feature vector. According to the method, the evaluation index is steady, and in addition, the hitting precision of the air-ground missiles of the same type can be evaluated, and the hitting precision of the air-ground missiles of different types can also be evaluated.

Description

technical field [0001] The invention belongs to the field of system performance evaluation, in particular to an error spectrum-based air-to-ground missile hit accuracy evaluation method. Background technique [0002] The hit accuracy of the air-to-ground missile system directly reflects the statistical characteristics of the air-to-ground missile's impact point and target aiming point. Commonly used weapon accuracy indicators include Accuracy, Precision and Circular Error Probability (CEP). Accuracy refers to the degree of deviation of the center of the impact point relative to the target aiming point; density refers to the degree of dispersion of the impact point relative to the center of dispersion; CEP refers to the center of a circle with the center of the impact point as the center, and the impact point falls into the circle. When the probability is 50%, the radius of the circle is the value of CEP. [0003] In hit accuracy evaluation, traditional statistical methods ...
