Rough North Correction Estimation Algorithm Based on Terrain Visibility

The article describes an innovative algorithm of a radar north correction estimation. The uniqueness of the algorithm is the pure data/software nature without need for any additional north-seeking equipment. This procedure is a key step of a registration local coordinate system to a global one. The...
