Abstract:

A mathematical model of a digitalization leveling platform for a radar is established and its corresponding algorithm is presented.Since the algorithm for traditional coordinate rotating transformation is complex,it is difficult to implement because of its heavy operand.Therefore,a novel algorithm is presented.This algorithm aims at dismantling the 3 dimensional mathematical model into the 2 dimensional model equivalently to carry out planar geometry parsing.Several simple equations are summarized after analysis so as to make the algorithm simple and easy to understand.This model can be applied in multiple fields such as phased array radars and gun firings,which are not leveled mechanically.
