Abstract
In this paper, the waveforms and signal processing for a high-accuracy X-Band microwave ranging system that enables a non-cooperative, open-loop coherent distributed radio frequency transmission system are presented. This sub-centimeter-accurate ranging system leverages a Two-Tone Continuous Wave (TTCW) signal as opposed to the conventional Linear-Frequency Modulated (LFM) waveform for ranging. Measurements for the TTCW are shown to achieve better accuracies than a LFM waveform given the same bandwidth and signal to noise ratio.
