PROBLEM TO BE SOLVED: To provide an angle-measuring device capable of very accurately measuring an angle of an arrival direction of an electric wave regardless of the modulation system of the electric wave emitted by an electric wave radiation source.SOLUTION: An amplitude standard section 4 for standardizing an amplitude of digital reception signals x(t), x(t) output from receivers 3-1 to 3-2 according to the amplitude of the digital reception signal x(t) output from the receiver 3-1 is installed, and a signal processing section 5 estimates an arrival direction of an electric wave emitted by an electric wave radiation source with the use of the digital reception signals x(t), x(t) whose amplitudes are standardized by the amplitude standard section 4. |
