A combined-radar transceiver is constructed which enables target ranging in both linear and nonlinear harmonic receive modes. The transceiver is constructed using an arbitrary waveform generator as the signal source, a high-speed digitizing oscilloscope as the signal capture device, and commercial off-the-shelf COTS components for the radar front-end. A length of Subminiature Version A SMA cable terminated in an open circuit simulates a linear radar target the same cable terminated in an SMA-connectorized radio front-end simulates a nonlinear radar target. A graphical user interface is developed in MATLAB to control the transceiver remotely. Ranging to the target is demonstrated experimentally using radiofrequency pulses, linear chirps, and stepped-frequency waveforms.
