Combined Linear and Nonlinear Radar: Waveform Generation and Capture

Abstract

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.
