Abstract

The present invention provides a method and system for evaluating ground target real-time tracking performance. The method includes: obtaining the estimation error probability distribution of a target estimator, and the target estimator is a ground target real-time tracking state estimator to be evaluated; analyzing the estimated The similarity between the error probability distribution and the preset expected error probability distribution; performing tracking performance evaluation on the target estimator according to the similarity. The present invention realizes the effective evaluation of the quality of different state estimators by using the similarity of the measurement error distribution relative to the expected reference quantity, that is, the expected level measurement, and further realizes the objective and fair evaluation of the ground target tracking state estimation technology.

Description

technical field [0001] The invention relates to the technical field of performance evaluation of ground target tracking state estimation technology, in particular to a method and system for evaluating ground target real-time tracking performance based on estimation error distribution. Background technique [0002] With the rapid development of modern high-precision sensor technology, in the process of real-time tracking of ground targets, the need for verification and evaluation of tracking algorithm performance is becoming more and more urgent. Accurate tracking algorithm performance verification and evaluation methods can help engineers select filters that meet performance requirements and improve tracking performance. [0003] At present, the verification and evaluation methods for the performance of existing tracking algorithms are realized by calculating the root mean square of the estimation error between the real state of the target and the estimated state. However, ...
