According to the invention, the signal spectrum measurement, and in the radio wave measuring apparatus for direction estimation of the signal, variable selected for the reference antenna from avoiding the radio wave shielding possible antenna arrangement for a possible signal arrival direction with respect to the receiving channel, other than the antenna by measuring the propagation through the channel multiplexed with respect to the arrangement, the electric wave shielding reduce the effect and, a dual-channel phase - and reduce the noise by using the spectrum analysis and a dual-channel cross-spectrum, and better measure the signal arrival direction with respect to the channel signal so can.
