<p>Disclosed is a system for detecting a covert object, comprising: a harmonic generating amplifying unit to generate and amplify multiple harmonics and to generate multiple middle frequency signals by respectively coupling the amplified harmonics and the harmonics; a bandwidth setting unit to receive the harmonics from the harmonic generating amplifying unit and to mix multiple bandwidth signals having predetermined bandwidths with the corresponding harmonics among the harmonics to generate multiple mixed harmonics; a harmonic transmission and antenna unit to adjust respective bandwidths of the mixed harmonics, to radiate the mixed harmonics having the adjusted bandwidths, and to receive multiple reflective waves in which the mixed harmonics are respectively reflected on objects; a harmonic receiving unit to compare the reflective waves and the corresponding middle frequency signals in the middle frequency signals and to analyze locations and RCSs of the objects for the reflective waves to obtain object analysis information; and a bandwidth control unit to generate multiple bandwidth signals to be transmitted to the bandwidth setting unit and to determine a harmonic to maximize the RCS of the object among the harmonics using the object analysis information obtained by the harmonic receiving unit.</p> |
