<p><P>PROBLEM TO BE SOLVED: To provide an angle measuring device capable of realizing independent monopulse angle measurement of an elevation angleθ, even when unequal interval disposition is applied to a three-dimensional antenna arrangement. <P>SOLUTION: Antenna elements 2 and 3 are divided into two regions so as to correspond to two antenna element groups of linear array antennas in a vertical direction. Composing sections 5 and 6 generate a difference signalΔand a sum signalΣfor a reception signal of the two regions. A dividing section 7 divides the difference signalΔby the sum signalΣ, and an angle measuring section 8 performs monopulse angle measurement of an elevation angleθby using a calculation result of the division section 7. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
