Abstract:

A simultaneous-frequency nonlinear radar is presented for detecting radio frequency electronic targets of interest. The radar transmits 20 frequencies tones between 890 and 966 MHz, at approximately equal amplitudes and evenly spaced 4 MHz apart. The radar transceiver and the target are connected by coaxial cabling as a hardware simulation of a wireless channel. The radar receives intermodulation produced by these 20 frequencies, in a 90-MHz band just below 890 MHz and another 90-MHz band just above 966 MHz. An inverse Fourier transform of this intermodulation demonstrates successful detection and ranging of each electronic target at a distance i.e., cable length of just over 50 ft.
