Bistatic Landmine and IED Detection Combining Vehicle and Drone Mounted GPR Sensors
2.2.1. Field Computation
3.1. Scenario Configuration
- Multimonostatic, where the TX–RX (drone mounted transceiver) is placed at 65 different positions between down-track positions m and m at m height. The angle of incidence is (i.e., the antennas are aligned perpendicular to the soil surface, with main beam pointing straight down).
- Multistatic, where the TX is placed at a fixed position (on a vehicle, at down-track position m and height m) with main beam pointing at an angle of incidence of with the nominal ground surface, and the drone-mounted RX is looking downward and is moved to the same positions as in the multimonostatic case.
- Multibistatic, where the vehicle-mounted TX is placed at m height and is moved between down-track positions m and m and the drone-mounted RX is moved between the same positions as in the multimonostatic case. Thus, both TX and RX are moved coherently. The angles of incidence are for the TX and for the RX.
