11. A radar system comprising:
a first antenna configured to generate and emit an incident signal having a first frequency;
a transponder tag attached to an existing portable object, said transponder tag including an electromagnetic nonlinear element being configured to be detected by said incident signal;
wherein upon being detected by said incident signal, said transponder tag being configured to transmit a reflected return harmonic signal having a second frequency different from said first frequency; wherein said reflected return harmonic signal is an on-off keying (OOK) signal; and
a second antenna configured to receive said reflected return harmonic signal having said second frequency; wherein said transponder tag includes a conductive layer in electrical communication with said electromagnetic nonlinear element, wherein said electromagnetic nonlinear element includes a Schottky diode.
