<p>PROBLEM TO BE SOLVED: To facilitate the detection of the radio waves of an organismic body and the like in the interior of fallen building and the like. SOLUTION: A compact antenna 2 is attached to the tip of a beam-shaped supporting member 1 so that the antenna can be readily inserted into the gaps of the remains, tiles and pebbles or the like of the fallen buildings. As the typical dimensions of the entire body of the antenna and the supporting member, the length is about 1 meter, and the maximum dimension in the vertical direction with respect to the longitudinal direction is set at 15cm or less. It is advantageous that flexibility is imparted and a bendable joint or a joint part is provided in the supporting member 1. In receiving circuit, the part, wherein the phase and the amplitude of one part of the transmitting signal are adjusted, is subtracted from the received signal so as to suppress the signal of the reflected wave from a static body.</p> |
