Problems solved by technology

In this process, the situation data as the true value is generated by artificial scenarios, which cannot present the real battlefield situation; while sensor simulation generally processes data by manually adding noise, clutter, etc. There are also some differences between
Taking this simulation data as input will affect the analysis results of the target characteristics during the development of the target track fusion algorithm, and even affect the fusion efficiency of the algorithm in real combat scenarios

Abstract

The invention belongs to the technical field of aircraft landing control, and particularly relates to a target track fusion evaluation method based on a data recharge function. The method comprises the following steps: acquiring local navigation data and local sensor measurement data; performing time alignment processing on the navigation data and the sensor measurement data; converting the navigation data and the sensor measurement data into a data format used in a target track fusion algorithm; simulating bus time, and recharging the processed sensor measurement data into target track fusionsoftware; and comparing the navigation data with a processing result of the target track fusion software, and evaluating a target track fusion algorithm. According to the application, a training datarecharging function is added, and a simulation system is allowed to use actual flight data as system input in an algorithm development process, so that the algorithm development and optimization workcan be performed more pertinently and more accurately.

Description

technical field [0001] The present application belongs to the technical field of track data processing, and in particular relates to a target track fusion evaluation method based on data feedback function. Background technique [0002] The target track fusion simulation system is a digital simulation system established for the development of the target track fusion algorithm, including functional modules such as situation simulation, sensor simulation, data feedback, fusion algorithm operation, and fusion result evaluation, covering the operation of the target track fusion algorithm the whole process. [0003] The input data of the traditional data fusion simulation system is mostly obtained by the system's own simulation. Through battlefield scenario generation and situation deduction, the track data is generated as the true value, and then the sensor measurement data is obtained through various sensor simulation processes. In this process, the situation data as the true v...
