Abstract

The invention discloses a probability hypothesis density filter radar system error fusion estimation method based on ADS-B. The method includes the steps that a radar system error observation equation based on ADS-B is set up; a radar system error state equation is set up; a radar system error state and observation finite set is constructed; error fusion estimation is conducted on a probability hypothesis density filter radar system. According to the estimation method, firstly, the ADS-B of a target and the observation of a radar are converted to be in a rectangular coordinate system with the radar as the center, due to the fact that the monitoring precision of the ADS-B is far superior that the positioning precision of the radar, on the basis of not considering the positioning error of the ADS-B, the radar system error observation equation and the radar system error state equation based on the ADS-B are set up, then a probability hypothesis density filter is used for conducting fusion estimation on the measuring difference of the ADS-B and the radar, and therefore an estimation result of the radar system error is obtained. The probability hypothesis density filter radar system error fusion estimation method has the advantages of being high in estimation precision, good in estimation performance and the like.

Description

technical field [0001] The invention belongs to the technical field of sensor error registration, in particular to an ADS-B-based probability assumption density filter radar system error fusion estimation method. Background technique [0002] Radar observation errors are mainly divided into random errors and systematic errors. In the multi-radar fusion tracking system, radar system error estimation has become a prerequisite for multi-radar fusion processing, which will directly affect the performance of the entire system. Therefore, it is necessary to estimate the radar system error, so as to compensate the radar measurement accordingly. This process is also called error registration. The existing radar error estimation methods can be classified into two categories: offline estimation methods and online estimation methods. Among them, the off-line estimation method is to estimate the systematic error through data fitting of the radar observation data for a period of time, ...
