A remote high-speed target radar tracking method based on primary-secondary composite filtering
By employing a master-slave composite filtering method, the position and radial velocity of a long-range high-speed target are estimated using extended Kalman and Kalman filters, respectively. This solves the range error problem caused by angle measurement errors in long-range high-speed target tracking and enables rapid and stable radar tracking.

Abstract
The present application relates to a kind of remote high-speed target radar tracking methods based on primary and secondary composite filtering, comprising: obtaining the measurement information of radar, the measurement information is converted to Northeast sky coordinate system, and first measurement information is obtained;According to first measurement information, the position information of remote high-speed target is estimated using first filter, and beam scheduling is realized using position information;Second measurement information is obtained according to position information, and the radial velocity of remote high-speed target is estimated using second filter according to second measurement information, and the radar tracking of remote high-speed target is realized.The remote high-speed target radar tracking method of the present application realizes the composite filtering method of primary and secondary combination by designing two filters, which is beneficial to phased array radar to realize accurate beam scheduling and distance doppler coupling compensation processing, and finally realizes the fast and stable tracking of remote high-speed target.
