Unlike monostatic radar where a single system transmits and receives reflected radio frequency (RF) energy, bistatic radar uses geographically separated radar transmitters and receivers.
In bistatic GNSS radar the transmitter is the GNSS satellite and the receiver is located on another satellite or airborne platform. This technique compares the direct and ground-reflected signals received from the GNSS satellite for remote sensing purposes. Possible applications include altimetry and ground feature characterization. This is a joint project between Luleå University of Technology and University of Colorado at Boulder, Colorado, USA.
