Locating Buried Bodies Using SAR Tomography

The Synthetic Aperture Radar operating in P-band and performing a helical flight pattern promises to be a potential tool for underground tomography, featuring high resolution and penetration. Based on the success of detecting ant nests beneath the industrial forest, a new experiment was carried out to detect buried bodies. Two sets of flights were performed and validated. Six bodies buried 0.5 m to 1.5 m deep, containing the remains of cow and pork, were located with a detection rate of 100% and a false alarm rate of 0%. Also, the ability to detect change across two sets of flights was verified by locating a bucket filled up with a large tarpaulin piece in the first set of flights.
