Abstract: Aiming at the problem of the deviation of the target information when taking the geographic north as the azimuth datum in the horizon target tracking in Arctic region (especially in the polar regions), a virtual method to re-partition the surface of the earth is proposed which can transform the geographic pole region into a virtual equatorial region. On the basis of the above, the transverse latitude and longitude grid, the transverse earth coordinate system and the transverse geographic coordinate system are constructed, The transverse geographic north is proposed as the azimuth datum, the target range is represented with the transverse azimuth in Arctic region, and the target tracking model based on the transverse earth coordinate system is constructed. The results of simulation analysis show that, the OTH (over the horizon) target tracking method based on the transverse earth coordinates can overcome the deviation of polar OTH target indication information brought by the meridian convergence in Arctic region.

Key words: Arctic region, OTH target tracking, transverse latitude and longitude grid, transverse earth coordinate system, transverse geographic coordinate system
