Stepped Frequency Radar

In the 1990s, RST introduced the highly efficient Stepped Frequency Radar. Originally designed as a forward-looking radar for planetary vehicles of the European Space Agency (ESA), it was finally used as Ground Penetration Radar (GPR) on earth. For the exploration of close-to-surface soil layers, RST perfected the path-breaking Stepped Frequency Technology.

Advantages compared to common short pulse GPRs:

better provides high bandwithds
carries out reflexion measurement in both absolute and phase value
sender and receiver feature the same high switching speed as short pulse technology
improved technology through bundled antennas with very high bandwith
operates on ground-based or airborne vehicles, as well as satellites and planetary orbiters
„gated“ Stepped Frequency GPRs allow for large penetration depths from flying platforms
