<p>PROBLEM TO BE SOLVED: To appropriately detect reflected wave even if the reflected wave is received at the same time with a carrier component signal. SOLUTION: A receiver antenna receives the carrier component signal, the reflected wave of the carrier reflected from the ground surface, and the reflected wave of the carrier reflected from an object expressed with a figure 7 (A), and receives a carrier component signal having an opposite phase to the carrier component expressed with the figure 7 (A) and generated by the carrier output from other receiver antenna. As a result, in the receiver antenna, the carrier component signals generated by the carrier output from each transmitter antenna are offset to each other, and a new radio wave is generated.</p> |
