Supplemental Information

Figure 1: Map of the sensor array geometry. MARU locations areshown as black, numbered circles.

DOI: 10.7287/peerj.preprints.322v1/supp-1

Figure 2: Spectrogramsof narrowband upsweep FM signals (NU).

The

spectrograms were obtained using 1024 point FFT with Hann window, 75% overlap, and

sampling rate of 5 kHz.
