Radio detection of meteors and other near-Earth targets by Zhang, Xiang

“…In this thesis, we report the investigation of intrinsic radio emission from meteors using the Murchison Widefield Array (MWA), and the detected reflection of FM broadcasting signals from satellites. We also discussed ground-based radar detection of near-Earth asteroids and generated models from delay-Doppler images.…”

On the detection and tracking of space debris using the Murchison Wdefield Array. I. Simulations and test observations demonstrate feasibility by Tingay, Steven, Kaplan, D.L., McKinley, B., Briggs, F., Wayth, Randall, Hurley-Walker, N., Kennewell, J., Smith, C., Zhang, K., Arcus, W., Bhat, Ramesh, Emrich D., Herne, D., Kudryavtseva, N., Lynch, M., Ord, S.M., Waterson, M., Barnes, D.G., Bell, M., Gaensler, B.M., Lenc, E., Bernardi, G., Greenhill, L.J., Kasper, J.C., Bowman, J.D., Jacobs, D., Bunton, J.D., Desouza, L., Koenig, R., Pathikulangara, J., Stevens, J., Cappallo, R.J., Corey, B.E., Kincaid, B.B., Kratzenberg, E., Lonsdale, C.J., McWhirter, S.R., Rogers, A.E.E., Salah, J.E., Whitney, A.R., Deshpande, A., Prabu, T., Udaya Shankar, N., Srivani, K.S., Subrahmanyan, R., Ewall-Wice, A., Feng, L., Goeke, R., Morgan, E., Remillard, R.A., Williams, C.L., Hazelton, B.J., Morales, M.F., Johnston-Hollitt, M., Mitchell, D.A., Procopio, P., Riding, J., Webster, R.L., Wyithe, J.S.B., Oberoi, D., Roshi, A., Sault, R.J., Williams, A.

“…The FM broadcasts propagate into space, are reflected off debris in Earth orbit, and are received at the MWA. …”

Limits on radio emission from meteors using the MWA by Zhang, X., Hancock, P., Devillepoix, H., Wayth, R., Beardsley, A., Crosse, B., Emrich, David, Franzen, T., Gaensler, B., Horsley, L., Johnston-Hollitt, M., Kaplan, D., Kenney, D., Morales, M., Pallot, D., Steele, K., Tingay, S., Trott, C., Walker, M., Williams, A., Wu, C., Ji, J., Ma, Y.

“…We also report detections of other transient events, such as reflected FM broadcast signals from small satellites, conclusively demonstrating the ability of the MWA to detect and track space debris on scales as small as 0.1 m in low Earth orbits.…”

Multitarget passive coherent location with transmitter-origin and target-altitude uncertainties by Tharmarasa, R., Subramaniam, M., Nadarajah, Nandakumaran, Kirubarajan, T., McDonald, M.

“…Passive coherent location (PCL) systems, which use existing commercial signals (e.g., FM broadcast, digital TV) as the illuminators of opportunity, is an emerging technology in air defence systems. …”
