<p>PROBLEM TO BE SOLVED: To improve the speed of simulation of reception characteristics of an object, having an arbitrary form which receives radio waves. SOLUTION: Simultaneous equations for movement method, concerning only currents IAl -IAm of each element of a transmitting antenna, are solved. Current values obtained are used as constants, and simultaneous equations of the moment method concerning only currents IEl -IEn of each element of EUT are formed. LDU resolution of a left side coefficient matrix [ZEi ,j ] is preserved and reused. For each angle of the transmitting antenna, right side voltage terms only are re-calculated, and the simultaneous equations are solved. The reception characteristics are obtained from a current value to each angle.</p> |
