A New Method for Moving-Target HRRP via Double Step Frequency Verified by Simulation

Sensors, 2022
The stepped-frequency (SF) waveform is highly sensitive to the target motion, which induces range shift and echo spread in a high-range-resolution profile (HRRP).

Multi-perspective high range resolution profiles of landmines [PDF]

2015 IEEE Radar Conference, 2015
Landmine clearance is a severe and unresolved humanitarian issue. The development of low-cost, smaller, faster and lighter Ground Penetrating Radars (GPR), which can be mounted on unmanned platforms, will allow faster and safer 24/7 operations. This technology will make it possible to survey affected areas with more flexible trajectories and these will
